1 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3 * eval.h (scm_macro_eval_x): Removed declaration.
5 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
6 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
7 Renamed and made global.
9 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
10 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
12 * evalext.c, evalext.h: New files. Contain non-R5RS things
13 having to do with evaluation.
15 * evalext.c (serial-map): New procedure: Version of `map' which
16 guarantees that the procedure is applied to the lists in serial
18 (sequence->list): New syntax: Version of `begin' which returns a
19 list of the results of the body forms instead of the result of the
21 (scm_definedp, scm_m_undefine): Moved from eval.c
23 * evalext.h (scm_m_sequence_to_list): Added declaration.
25 * macros.c, macros.h: New files.
26 (procedure->syntax, procedure->macro, procedure->memoizing-macro,
27 macro?, macro-type, macro-name, macro-transformer): Moved from
29 (scm_make_synt): Moved from eval.c
31 * procs.c, procs.h (procedure-documentation): Moved from eval.c.
33 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
36 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
38 * debug.c, print.c: Added #include "macros.h".

42 This change adds the ability to use `unread-char' multiple times
43 without interspersed reads and adds the new procedure
44 `unread-string'. The change is optimized for the common case of
45 unreading a single character. This is also the reason behind the
46 choice to store characters in the port itself: in most cases no
47 extra malloc is required.
49 The amount of code in some macros in ports.h has been increased to
50 the extent that they would fit better as C functions, but, since
51 this code belongs to the port representation, such functions
52 should be placed in ports.c which would cause calls back and forth
53 between ports.c and genio.c. That is not good for performance.
54 Also, keeping them as macros allows the compiler to do some
55 optimizations which are needed to make the current interface
56 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
58 One benchmark (Guile startup time) indicates an increase of
59 loading speed of 1%. Another (reading (using `read') boot-9.scm
60 10 times) shows no change in performance.
62 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
63 made to find a beautiful solution.)
65 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
66 (SCM_TRY_CLRDY): New macro: Only clear the first unread
67 character. (SCM_CLRDY clears all.)
68 (SCM_N_READY_CHARS): New macro: Returns number of unread
69 characters in a port. Returns wrong answer if SCM_CRDYP is false.
70 (struct scm_port_table): New fields: `entry' contains port table
71 index, `cp' points to last unread char, `cbuf' is the buffer for
72 unread chars, `cbufend' points after end of the character buffer.
74 * ports.h, ports.c (scm_unread_string): New procedure.
75 (scm_grow_port_cbuf): New function.
77 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
79 (scm_generic_fgets), fports.c (local_fgets): Use a loop
80 to read unread characters. Use SCM_TRY_CLRDY instead of
83 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
85 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
87 * genio.c, genio.h (scm_ungets): New function.
89 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
92 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
94 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
95 declarations. (Thanks to Russ McManus.)
97 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
99 * numbers.c (num2long): As a software archeologist, I'm proud of
100 this finding! :) Preliminary dating suggests an almost 4 year old
101 remnant from the SCM ancestor. The sample has been removed from
102 the finding site and is now safely stored in the repository.
104 * numbers.h: Removed prototype for num2long.
106 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
108 * gh_data.c (gh_scm2doubles): Make it possible to pass result
110 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
111 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
112 * gh.h: Updated and added prototypes.
114 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
116 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
118 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
120 * guile-snarf.in: Never generate an empty file. (Thanks to
123 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
124 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
125 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
126 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
127 gh_new_procedure5_0): Specify argument types, to appease C++
128 compilers. (Thanks to Brad Bowman.)
130 Bug reports from Russ McManus:
131 * guile-snarf.in: If the CPP environment variable is set, use that
132 as the C preprocessor, instead of the preprocessor autoconf
134 * snarf.h (SCM_PROC): Cast the function pointer passed to
135 scm_make_gsubr, to satisfy C++.
137 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
138 Use the handler passed, instead of ignoring it and using
139 gh_standard_handler. (Thanks to Etienne Bernard.)
141 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
143 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

163 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
166 * script.c (scm_compile_shell_switches): Define
167 use-emacs-interface in the root module, so the repl code can see
168 it. See today's change to top-repl in ice-9/boot-9.scm.
170 * filesys.c (set_element, get_element): Make sure that `element'
171 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
172 Boekemeier and Jorgen "forcer" Schaefer.)
174 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
176 * chars.c (scm_charnames): In ASCII character name table, make
177 newlines print as #\newline by default, not #\nl.
179 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
180 alphabetical order. Oh thrills. But it helps me know how far
181 along in the compilation I am.
182 * Makefile.in: Regenerated.
184 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
186 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
187 #bytes(...) to #y(...), and syntax for short vectors from
188 #short(...) to #h(...). This may seem nutty, but, like the other
189 uniform vectors, byte vectors and short vectors want to have the
190 same print and read syntax (and, more basic, want to have read
191 syntax!). Changing the read syntax to use multiple characters
192 after the hash sign breaks with the conventions used in R5RS and
193 the conventions used for the other uniform vectors. It also
194 introduces complexity in the current reader, both on the C and
195 Scheme levels. (The Right solution is probably to change the
196 syntax and prototypes for uniform vectors entirely.)
198 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
200 Don't use local_fgets on sockets; ftell doesn't work on sockets.
201 (Thanks to Jorgen "forcer" Schaefer.)
202 * ports.h (SCM_NOFTELL): New flag.
203 * fports.c (local_fgets): If it's set, use the generic fgets.
204 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
206 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
208 * script.c (scm_compile_shell_switches): Add handling of -q switch
209 (inhibit loading of user init file).
210 (scm_shell_usage): Add usage text for -q switch.
211 (scm_compile_shell_switches): Always load user init file first if
214 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
216 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
217 and is now broken under NetBSD. I can't fathom what it's trying
218 to do, so I've replaced it with something that I do understand,
219 which seems to work, and which isn't broken on NetBSD. "Progress?
220 You Decide." (Thanks to Perry Metzger.)
222 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
223 signed/unsigned comparison.
225 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
227 Warning fixes from Greg Harvey:
228 * unif.c (scm_array_set_x): initializer for pos
229 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
230 * struct.c (scm_struct_ref, scm_struct_set_x): Added
231 initializers for field_type, since EGCS so desparately wants to
233 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
234 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
235 when GUILE_DEBUG is defined.
236 * dynwind.h (scm_wind_chain): Same.
237 * ports.h (scm_pt_size, scm_pt_member): Same.
238 * print.h (scm_current_pstate): Same.
239 * procs.h (scm_make_cclo): Same.
241 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
243 Handle short and long long uniform arrays properly. (Thanks to
245 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
246 raeql_1): Add cases for scm_tc7_svect (short vectors) and
247 scm_tc7_llvect (long long vectors).
249 Change the way libguile and boot-9.scm are timestamped, to try to
250 get rid of these spurious mismatch warnings. Now both
251 libguile/versiondat.h and ice-9/version.scm are generated directly
252 by the configuration process, rather than having version.scm
253 generated directly, and libguile/versiondat.h generated by the
254 Makefile, which is generated by configure. It seems that
255 sometimes the Makefile would change, but versiondat.h depends on
256 Makefile.in, not Makefile, so it wouldn't get rebuilt.
257 * Makefile.am (versiondat.h): Target removed; this is generated
258 directly by the configure script now.
259 (BUILT_SOURCES): Remove versiondat.h.
260 * versiondat.h.in: New file, transformed by the configure script
262 * Makefile.in: Regenerated.
264 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
265 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
266 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
267 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
268 if we want to use them in a header file some day, we can. (Thanks
271 * stime.c (scm_get_internal_real_time): Do the arithmetic using
272 SCM numbers, so we won't have rollover problems; the range of a
273 signed long in milliseconds is about 25 days. (Thanks to Karl
276 Don't redefine sleep and usleep; fix this problem now.
277 * coop.c (sleep, usleep): Remove declarations; we don't use or
278 redefine these any more.
279 (scm_thread_usleep, scm_thread_sleep): New functions which do the
280 job of usleep and sleep in a thread-friendly way. We can use
281 these in the rest of Guile. Define versions for systems both with
283 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
284 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
285 we're just using it, not redefining it, we can use a K&R style
287 (sleep): Declare this, too, if the system hasn't.
288 (scm_sleep, scm_usleep): Use scm_thread_sleep and
289 scm_uthread_sleep if they're available; otherwise, just call the
291 * scmconfig.h.in: Regenerated.
293 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
295 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
297 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
299 * threads.c: Doc fix.
301 The argument type of usleep varies from system to system,
302 as does the return type. We really shouldn't be redefining usleep
303 at all, but I don't have time to clean that up before the 1.3.
304 release. It's on the schedule for afterwards. (Thanks to Julian
306 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
308 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
309 * scmconfig.h: Regenerated.
311 * simpos.c (scm_software_type): Procedure deleted. This isn't the
312 right way to handle system variation. Autoconf's approach is the
314 * simpos.h (scm_software_type): Declaration deleted.
316 * script.c (scm_find_executable): Don't test if unix is #defined
317 here; first, NetBSD doesn't #define it, and second, it's the wrong
318 way to go about these things. (Thanks to Perry Metzger.)
319 (dld_find_executable): Delete this MSDOS support code. This isn't
320 the way we want to support this; it needs to be rethunk at a
323 * genio.c (scm_do_read_line): Don't just politely check that the
324 line was either non-empty or EOF. Abort if it's empty and not
327 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
329 * scmconfig.h.in: Regenerated.
331 * libguile.h: Don't omit the dynamic linking functions. (Thanks
334 * genio.c (scm_do_read_line): Count lines correctly when the file
335 doesn't end in a newline.
337 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
339 * genio.c (scm_do_read_line): Maintain the line count correctly.
340 (Thanks to Harvey J. Stein and Greg Harvey.)
342 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
345 * numbers.c (big2str): Protect t from garbage collection until
346 we're done. (Thanks to Gary Houston.)
348 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
350 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
352 * Makefile.in: Regenerated.
354 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
355 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
358 Do magic to mix reads and writes on stdio FILE-based ports.
359 (Thanks to Christian Lynbech.)
360 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
362 (pre_read, pre_write): New functions.
363 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
364 local_fputs): Call them.
365 (local_fflush): Mark the port as ready for reading and writing.
366 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
367 flags on new port objects. This might not be accurate --- who
368 knows what state the FILE * is in when we get it --- but it won't
369 do extraneous calls to fflush or fseek, so it's no worse than the
370 behavior before this change.
371 * ports.h: Add comment.
373 Centralize the creation of port objects based on stdio FILE * in
374 fports.c; don't just throw them together anywhere.
375 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
376 what the rest of Guile wants. Don't set the revealed count;
377 that's only appropriate for stdin, stdout, stderr.
378 (scm_standard_stream_to_port): This function does set the revealed
380 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
381 not scm_stdio_to_port.
382 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
383 * fports.c (scm_open_file): Same.
384 * posix.c (scm_pipe): Same.
385 * socket.c (scm_sock_fd_to_port): Same.
386 * ioext.c (scm_fdopen): Same.
387 (scm_freopen): Moved from here to...
388 * fports.c (scm_freopen): ... here. This is really something that
389 munges the internals of an fport, so it should go here.
390 * fports.h (scm_stdio_to_port): Adjust prototype.
391 (scm_standard_stream_to_port, scm_freopen): New protoypes.
392 * ioext.h (scm_freopen): Prototype removed.
394 * filesys.c (set_element, get_element): This can work on both pipe
395 and file ports, so use SCM_FPORTP to typecheck, instead of testing
398 * scmconfig.h.in: Regenerated.
400 Change the definition of the functions in scm_ptobfuns so that
401 they get passed the port object, not the port's stream.
402 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
403 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
404 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
405 Pass the port itself to the scm_ptobs function.
406 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
407 scm_generic_fgets): Same.
408 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
409 getc_void_port, fgets_void_port, close_void_port): Just change the
410 argument names; these functions don't really do anything.
411 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
412 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
413 port as an argument, and use SCM_STREAM to get the stdio FILE *.
414 Also, use prototyped definitions, and get rid of the extra
416 (scm_fptob, scm_pipob): We don't need casts here any more.
417 * strports.c (prinstpt): Use prototype declarations.
418 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
419 and use SCM_STREAM to get the string info. Also, use prototyped
420 definitions, and get rid of the extra declarations.
421 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
424 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
425 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
427 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
428 scm_fgets, for consistency.
429 (scm_fptop, scm_pipob): References updated.
431 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
433 Include the source location in error messages for scripts.
434 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
435 stack is still there when we catch the error.
436 * throw.c (handler_message): If we are handling an error with a
437 message, then put together the proper arguments and call
438 scm_display_error, instead of scm_display_error_message. That
439 displays source location, if it can find it.
441 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
443 * gc.c (scm_unprotect_object): Change this so that calls to
444 scm_protect_object and scm_unprotect_object nest properly.
445 (scm_protect_object): Doc fixes.
447 * strings.c (scm_string_set_x): Require the argument to be a
448 writable string, not a substring or a symbol.
449 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
450 (Thanks to John Redford and Charbel Jacquin.)
452 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
454 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
456 * eval.c (safe_setjmp): Remove this misunderstanding.
457 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
460 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
462 * libguile.h: Mark these as C declarations, for compilation by C++
465 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
466 __cplusplus clause. I seriously doubt this ever worked the way
467 the author seems to have intended.
469 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
471 Utterly needless cleanups to hopelessly messy code.
472 * ports.c: Doc fixes.
473 (scm_fflush): Moved to ...
474 * genio.c (scm_fflush): ... here, amongst all the other port
475 method invocation functions.
476 * genio.h, ports.h: The prototype moves too.
478 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
480 * backtrace.c (display_error_body): The current frame does not
481 always have a parent frame; consider a function called directly
482 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
485 * alloca.c (alloca): Undo yesterday's changes, and simply call
486 malloc directly for storage, and abort if we don't get what we
487 want. The situation is much simpler --- just call malloc. Emacs
488 has bizarre/evil requirements (signal handlers might malloc unless
489 you set this global flag, so you have to set the flag around all
490 calls to malloc) which we are certainly not going to conform to,
491 so we can do the simple and obvious thing.
493 * coop.c (coop_condition_variable_wait): Make this function
494 static. It's only useful internally --- you should never just
495 wait on a condition variable.
496 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
498 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
500 * unif.c (scm_array_set_x): Accept any kind of number as an
501 element for a uniform vector of doubles. This is more consistent
502 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
504 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
505 works; I can't conveniently test it myself. (Thanks to Dvid
506 Tillman for the bug report.)
510 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
511 from here, not from scm_compile_shell_switches (which is a pretty
512 dumb place to do it).
513 (scm_load_startup_files): New function.
514 (scm_ice_9_already_loaded): Variable moved to here from script.c.
515 * script.c (scm_compile_shell_switches): Don't load the startup
517 (scm_ice_9_already_loaded): Variable moved.
518 * init.c (scm_load_startup_files): Prototype for new function.
519 * gh_init.c (gh_enter): Doc fix.
521 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
523 Some anti-warning changes from Greg Harvey.
524 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
525 warnings when it doesn't understand our NORETURN declarations in
527 * posix.c (scm_mknod): Similar.
529 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
531 * posix.c (scm_getpwuid): If we can't find an entry, return our
532 own message, instead of using scm_syserror --- the getpwMUMBLE
533 functions don't set `errno' to anything interesting.
535 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
537 Get rid of warnings from the cooperative threading system.
538 * threads.h (scm_single_thread_p, scm_yield,
539 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
540 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
541 scm_wait_condition_variable, scm_signal_condition_variable): Add
542 prototypes for these Scheme-visible functions.
543 * coop-defs.h (coop_next_runnable_thread,
544 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
545 Prototypes for these here, even though they're from iselect.c.
546 (coop_condition_variable_wait, coop_join): Add prototypes.
547 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
548 scm_threads_free_condvar): Make these smob functions static.
549 * coop-threads.h (coop_init): Give this a real prototype.
550 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
551 (coop_next_runnable_thread): No need to provide prototype; it's in
554 * scmconfig.h.in: .detarenegeR
556 * iselect.c, threads.c: Doc fixes.
558 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
560 * Makefile.in: Regenerated with a patched automake, to get
561 dependency generation right when using EGCS.
563 * inet_aton.c (inet_aton): Add prototype, to remove compiler
564 warning. (Thanks to Robert Pluim.)
566 * inet_aton.c (inet_aton): Reassure the compiler that the
567 arguments to the <ctype.h> macros are all unsigned characters, not
570 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
572 Getting rid of more warnings...
573 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
574 today's change to ../configure.in.
575 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
576 * scmconfig.h.in: Regenertaded.de.,.__
577 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
578 (scm_localtime, scm_mktime): Use a const char * to manipulate the
581 * readline.c: Doc fix.
582 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
583 * readline.h (scm_filename_completion_function): Add prototype.
584 (scm_init_readline): Make this into a prototype.
586 * readline.c (scm_filename_completion_function): Use SCM_PROC to
587 declare this, instead of calling scm_make_subr manually.
589 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
591 * readline.h (scm_init_readline): Add prototype for this.
592 (scm_init_readline): Make this a real prototype.
594 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
596 Warning fixes from Maciej Stachowiak:
597 * backtrace.h (scm_display_application, scm_backtrace): Add
599 * debug.c (scm_m_start_stack): Make this function static.
600 * fluids.h (scm_fluid_p): Add prototype.
601 * procprop.c (scm_i_procedure_arity): Make this function static.
602 * regex-posix.c (scm_regexp_error_msg): Make this function static.
603 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
604 * root.h (scm_dynamic_root): Add external prototype.
605 * scmsigs.h (scm_usleep): Add external prototype.
606 * script.h (scm_init_script): Use prototype, not K&R decl.
607 * stacks.h (scm_stack_id): Add external prototype.
608 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
610 1998-09-30 Mark Galassi <rosalia@cygnus.com>
612 * gh.h: took out the definitions of vset and vref, since they are
613 replaced by the proper vector routines that correspond to the R4RS
616 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
618 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
619 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
620 third argument, a C expression that should result in a SCM value,
621 which is used to initialize the variable. Reimplemented
622 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
625 * version.h (scm_libguile_config_stamp): Add prototype.
626 (From Maciej Stachowiak.)
628 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
630 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
631 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
633 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
635 * print.c (scm_iprin1): Rather than having one i, and using it in
636 several places, declare a fresh i local to each block where it is
637 used, and give it a signedness appropriate to its use in each case.
640 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
643 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
644 signed/unsigned clashes.
646 * posix.h (scm_tmpnam): Added prototype.
648 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
649 scm_make_subclass_object): Add external prototypes.
651 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
652 comparison is okay here.
654 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
656 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
657 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
659 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
662 * load.c (swap_port): Make this function static.
664 * load.c (scm_search_path): Make max_path_len and max_ext_len
665 unsigned, since they're compared against string sizes.
667 * load.c (init_build_info): Make i unsigned.
669 * ioext.h (scm_read_line): Add prototype.
671 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
672 scm_hash_fn_remove_x): Make hash bucket index local variable k
673 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
674 accurately as possible.
676 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
677 comparisons, and range checking to make sure those casts are
680 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
681 signed/unsigned comparisons.
683 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
684 avoid signed/unsigned comparisons.
685 * smob.h (scm_numsmob): Change extern declaration to match.
687 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
688 avoid signed/unsigned comparisons.
689 * ports.h (scm_numptob): Change extern declaration to match.
690 (scm_current_load_port, scm_set_port_line_x,
691 scm_set_port_column_x): New prototypes.
693 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
694 test code, and it causes warnings.
696 * gh.h (gh_int2scmb, gh_uniform_vector_length,
697 gh_uniform_vector_ref): Added prototypes.
699 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
700 debugging support unconditionally. That's backtrace.c, stack.c,
701 debug.c, and srcprop.c.
702 (EXTRA_libguile_la_SOURCES): Omit those from here.
703 * Makefile.in: Regenerated.
705 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
707 * options.c (scm_options): Bugfix: Allow empty list of options!
709 * debug.c, debug.h (scm_single_step): Removed.
710 (scm_with_traps): New procedure. This procedure could easily be
711 written in Scheme but needs to be highly optimized.
713 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
715 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
716 Check SCM_TRAPS_P before trapping.
718 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
720 Changes to avoid signed/unsigned comparison warnings.
721 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
722 (scm_gc_sweep): Make n and j local to the blocks they're used in,
723 so they can have appropriate types for each application. Make i
724 signed. Use initializers in some spots. I'll probably pay for
726 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
727 (scm_must_realloc): Make nm unsigned.
728 (init_heap_seg): Make new_seg_index and n_new_objects signed.
729 (scm_init_storage): Use prototype-style definition, and make the
731 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
732 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
734 * filesys.c (scm_readlink): Make local vars rv and size ints, to
735 avoid signed/unsigned comparison warnings, and because the return
736 value of readlink may be -1. Don't bother casting the third
737 argument to readlink.
739 * filesys.c (scm_dirname, scm_basename): Move these to their own
740 page, at the end of the file.
741 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
743 * eval.h (scm_eval_options_interface): Add external prototype for this.
744 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
746 * eval.c (scm_lookupcar1): Make this static.
748 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
749 Make these prototype declarations, not K&R-style.
751 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
752 unsigned comparison warning.
754 * appinit.c: File removed. It had a single function in it, empty,
755 whose reason for existence is explained in no documentation or
756 comment. I think it's there as a default for some Tcl-style
757 initialization, but Tcl abandoned that approach a while ago.
758 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
759 (BUILT_SOURCES): Remove appinit.x.
760 * Makefile.in: Regenerated.
762 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
764 * Makefile.in: Regenerated using the last public version of
765 automake, not the hacked Cygnus version.
767 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
769 Remove Totoro kludge.
770 * Makefile.in, scmconfig.h.in: Regenerated.
771 * init.c, readline.c: Don't check if TOTORO is #defined.
773 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
775 * Makefile.am: Adjust for new thread configuration system.
776 (INCLUDES): Include the value of THREAD_CPPFLAGS.
777 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
779 (THREAD_LIBS): Definition deleted; automake will generate such
780 things automatically.
781 * Makefile.in: Regenerated.
783 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
785 Simplify smob and port marking; set the mark bit in the generic
786 marking code, and make marker routines only responsible for
787 turning up outgoing pointers.
788 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
789 before calling the marking function. Don't call the marking
790 function if it's zero.
791 * markers.c (scm_mark0): Just return #f. This function isn't
792 necessary at all now, but it's harmless to call it. We'll leave
793 it in so other folks' code doesn't croak at link time.
794 (scm_markcdr): Don't call SCM_SETGC8MARK.
795 * async.c (mark_async): Don't call SCM_SETGC8MARK.
796 * dynl.c (mark_dynl_obj): Same.
797 * root.c (mark_root): Same.
798 * srcprop.c (marksrcprops): Same.
799 * unif.c (markra): Same.
800 * variable.c (scm_markvar): Same.
801 * ports.c (scm_markstream): Same.
802 (void_port_ptob): Specify zero for our marking function.
803 * debug.c (debugobjsmob): Same.
804 * dynwind.c (guardsmob): Same.
805 * filesys.c (dir_smob): Same.
806 * fluids.c (fluid_smob): Same.
807 * fports.c (scm_fptob, scm_pipob): Same.
808 * mallocs.c (mallocsmob): Same.
809 * regex-posix.c (regex_t_smob): Same.
810 * smob.c (freecell, flob, bigob): Same.
811 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
812 * throw.c (jbsmob, lazy_catch_funs): Same.
814 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
816 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
817 scm_copy_tree on code in order not to let memoized code to leak
818 out. Thus, scm_copy_tree needs to copy vectors as well since
819 quasiquote can introduce evaluated code also inside vector
822 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
824 * eval.c (scm_copy_tree): Removed ability to copy vectors.
826 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
827 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
830 * unif.c: Say that ivect and uvect are of type signed and unsigned
831 long instead of int in commentary so that it correctly describes
834 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
836 * stime.c: Removed declaration of strptime. (It should be
837 declared by the system headers. If it turns out that some systems
838 don't, we'll handle that then.) (Thanks to Greg Troxel.)
840 * stime.h: Renamed TIMEH --> STIMEH
842 * backtrace.c (scm_display_error, scm_display_backtrace): In order
843 to increase portability, don't use structure assignment.
844 (Thanks to Nicolas Neuss.)
846 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
848 (finalize_fd_sets): Added empty statement after last case label.
849 (Thanks to Nicolas Neuss.)
851 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
854 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
856 * init.c, readline.c: OK, I won't have these readline.x bug
857 reports anymore. We've had them since April. The current reason
858 is a completely unintelligible failure of totoro.red-bean.com to
859 do the test for rl_getc_function in libreadline correctly. This
860 kludge overrides the test if we're on totoro so that the snapshot
861 generation process can work.
863 * readline.c: Define a strdup replacement if not existent on system.
865 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
867 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
868 This change makes scm_make_vector R5RS compatible. We cannot keep
869 the third argument since people want to be able to deduce the form
870 of the C function call only by looking at R5RS. (At the same time
871 we have removed some unnecessary complexity!)
873 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
874 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
875 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
876 argument in call to scm_make_vector.
878 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
880 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
881 This macro is useful in applications.
883 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
885 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
886 (scm_parse_path, scm_search_path): New Scheme level procedures.
888 * load.h (scm_internal_parse_path, scm_parse_path,
889 scm_search_path): Declared.
891 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
893 * filesys.c (dirname, basename): New procedures.
895 * init.c (scm_boot_guile_1): Removed condition around
898 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
899 new data type (guards) for representation of C level guards and
900 data on the wind chain.
901 (scm_internal_dynamic_wind): New function.
903 * dynwind.h: Declare scm_internal_dynamic_wind.
905 * root.h (scm_root_state): Added scm_cur_loadp.
907 * root.c (mark_root): Added comment about cur_loadp.
909 * load.c: #include "dynwind.h";
910 (scm_primitive_load): Use scm_inner_dynamic_wind to update
913 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
915 * ports.c (current-load-port): New procedure.
917 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
919 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
920 not a tty, return #f.
922 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
923 to Julian Satchell and Roland Kaufmann.)
925 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
926 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
928 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
930 * debug.h, debug.c (scm_start_stack): New function. Implements
931 the guts of old scm_m_start_stack.
933 * debug.c (scm_m_start_stack): Use scm_start_stack.
935 * init.c (scm_start_stack, scm_restart_stack): Renamed to
936 start_stack and restart_stack. (These have static scope.)
938 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
940 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
941 readline functions to come in release 2.3. (Thanks to Chet
943 (handle_errors): Use the above functions.
945 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
947 * readline.c: Improvements for readline support: Handle errors
948 better; Implement before-read-hook.
950 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
952 * init.c (scm_boot_guile_1), readline.c: Test for
953 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
954 assure that we have version >= 2.1.)
956 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
958 * readline.c (scm_readline): Defer interrupts while we're calling
961 * readline.c (scm_add_history): Bugfix: Do strdup before giving
962 away the string to add_history.
963 (completion_function): Do completion for readline. (Thanks to
965 (scm_filename_completion_function): New procedure: Filename
967 (current_input_getc): New function. Use this one instead of
968 standard getc from readline.
970 * throw.c, throw.h (scm_handle_by_throw): New function: This
971 handler throws errors to next handler on the dynwind chain.
973 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
975 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
978 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
980 * procprop.c (scm_i_procedure_arity): New function. Returns arity
982 (scm_procedure_properties): Modified to return arity together with
984 (scm_procedure_property): Added the read-only property `arity'.
985 (scm_set_procedure_property_x): It is an error to set the `arity'
988 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
989 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
991 * procprop.h (scm_sym_arity): New symbol.
993 * objects.c (scm_set_object_procedure_x): New procedure: Use this
994 to set the dispatch procedure of an operator or entity object.
996 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
997 Made procedure slots read-only.
999 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
1000 scm_tcs_cons_gloc case in zero args switch; Fixed args
1001 construction for operators in scm_tcs_cons_gloc case in two args
1004 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1006 * fluids.c: Removed use of assert.h (in order to avoid
1009 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
1011 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
1013 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
1014 change makes the evaluator safer at the cost of evaluation speed.
1015 It handles the case when the user has added a non-immediate
1016 improper end of the application form, e.g., `(+ 0 . x)'.
1017 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
1018 minimize the extra cost as much as possible. The new code is
1019 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
1020 problem with structs planted directly in the code (e.g. by a
1021 macro). This no longer causes segmentation fault. (Thanks to
1024 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
1025 arg `proc' in order to be able to throw errors; New argument
1028 * Removed extra #include "debug.h"
1030 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
1032 * scmsigs.c: Declare usleep as returning void on some systems.
1033 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
1036 * coop.c (usleep): Return void on some systems.
1038 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1040 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
1042 * coop.c: Changed return type of usleep to int.
1044 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
1045 isn't found in the OS.
1047 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
1048 isn't enabled. (Thought that I had made this change ages ago...)
1050 * iselect.c: Declare bzero if not defined by OS.
1052 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1054 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
1055 condition. (Thanks to John Tobey.)
1057 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
1058 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
1061 * __scm.h: Start the long-term project of moving to POSIX threads.
1062 Phase 1: Classification of all critical sections.
1063 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
1064 for A sections. (See comments in __scm.h for details.)
1066 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
1067 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1069 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1071 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
1072 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
1073 (libpath.h, versiondat.h): Replaced dependency on Makefile with
1074 dependencies on $(srcdir)/Makefile.in
1075 $(top_builddir)/config.status in order to avoid circularity.
1077 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
1078 from argc if argc was 0 initially.
1080 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
1081 in generation of libpath.h.
1083 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
1085 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
1086 libguile from 2 to 3.
1088 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
1090 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1092 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1094 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1095 scm_set_port_column_x, scm_port_filename,
1096 scm_set_port_filename_x): Removed optional arguments. Added
1097 proper argument checking.
1099 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1100 stack size in machine words.
1102 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1103 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1104 to Ole Myren Röhne.)
1106 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1108 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1109 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1111 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1114 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1115 procedure apply: Copy argument lists before pushing them unto the
1116 environment so that the environment won't get mutated due to
1117 manipulation of procedure arguments. This should perhaps be
1118 regarded as a temporary solution until someone finds a more
1119 efficient one. (Thanks to Maciej Stachowiak.)
1121 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1123 * script.c (scm_compile_shell_switches): Use "guile" as default
1124 zero arg if argc is NULL.
1126 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1128 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1129 is zero. (Thanks to Dirk Herrmann.)
1131 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1133 * ports.c (scm_add_to_port_table): First line is now line 0
1134 (was 1). (Interface changed according to suggestion by Per
1137 * backtrace.c (display_header): Add 1 to line and column numbers
1138 when presenting them to the user.
1140 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1141 from debug.c --> eval.c
1143 * eval.h, eval.c (scm_eval_options_interface): New options
1145 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1146 i.e. stacks for new threads.
1148 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1150 * eval.c (unsafe_setjmp): Removed with #if 0.
1152 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1155 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1156 to avoid compiler warnings.
1158 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1160 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1162 * throw.c (handler_message): Print message on current error port
1163 instead of default error port. (Thanks to Maciej Stachowiak.)
1165 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1167 * ports.c (scm_add_to_port_table): allocate in units of
1168 struct scm_port_table *, not struct scm_port_table.
1169 * posix.c (scm_close_pipe): remove the port from the port table
1171 Thanks to Rob Engle for both fixes.
1173 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1175 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1176 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1178 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1180 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1182 * backtrace.c (display_error_body, display_backtrace_body),
1183 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1184 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1185 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1186 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1189 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1190 don't receive the jmpbuf arg anylonger.
1191 (scm_catch): Don't accept a #f tag.
1192 (scm_throw): Check that key is a symbol.
1193 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1195 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1197 * async.c (async_pending): Removed declaration.
1199 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1201 * dynwind.c (scm_wind_chain): New debug function.
1203 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1204 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1205 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1206 extra layer of functions around the body and handler of a thread.
1207 This extra layer makes sure that the handler is called in the
1208 dynamic context of the surround (= empty dynwind list), but under
1209 the *dynamic root* of the body. We can not use the dynamic root
1210 of the surround since that root belongs to another thread => stack
1211 is not handled correctly. It may seem ugly to use this extra
1212 layer, but the extra cost in terms of execution time is really
1213 negligible compared to the total amount of time required to create
1214 a thread, and it would reduce maintainability to duplicate the
1215 crucial and complicated steps performed by cwdr.
1217 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1218 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1219 get re-enabled. The important effect of this is that interrupts
1220 are blocked during thread switching so that thread data structures
1221 don't risk getting messed up by an unfortunate signal.
1222 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1223 seems to do more aggressive optimization which actually move
1224 instructions around in these macros in a fatal way. Therefore:
1225 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1226 just superstitious...)
1227 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1228 This macro should be used instead of SCM_ASYNC_TICK since the
1229 latter doesn't do context switches any more.
1231 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1232 instead of SCM_ASYNC_TICK.
1234 * coop.c, iselect.c: Since thread switches are now performed with
1235 interrupts masked, we can't use the old mechanism of delivering
1236 signals immediately when they arrive. Signals must instead be
1237 delivered when the asyncs run *after* the end of the critical
1238 section in scm_internal_select. But this also means after context
1239 switch so that the signal will be delivered to a different thread.
1240 To avoid this, I have changed the protocol of
1241 coop_wait_for_runnable_thread and friends so that they are allowed
1242 to return the original thread. So, if a signal arrives during
1243 scm_internal_select, we won't any longer be forced do a context
1244 switch, but can remain in the same thread and deliver the signal
1247 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1248 scm_asyncs_pending and made it global.
1250 * iselect.c: Small fixes.
1252 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1253 coop_condition_variable_init, coop_condition_variable_wait,
1254 coop_condition_variable_signal): Changed return type from `void'
1255 to `int'. This is to adhere closer to the pthreads interface.
1256 This, in turn, is part of an attempt to provide C versions of the
1257 mutex and condition variable primitives which can be part of a
1258 frontend to COOP or pthreads.
1260 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1261 coop_condition_variable_destroy): New functions.
1263 * coop-threads.c (scm_wait_condition_variable): Use
1264 coop_condition_variable_wait_mutex.
1266 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1267 Definitions moved to coop-defs.h.
1269 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1270 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1271 scm_cond_destroy): New C interface to mutecis and cond vars.
1273 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1275 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1277 * iselect.c: Now several threads can wait on the same file
1278 descriptor. The behaviour is compatible with OS select: All
1279 threads waiting for the fd return with the same status.
1281 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1283 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1284 Can spawn a thread from application C code.
1286 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1288 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1289 gh_doubles2scm): New functions.
1291 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1293 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1294 commented-out version of gh_eval_str()
1296 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1298 * socket.c (scm_bind): free soka after use.
1300 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1302 * stime.c (tzvar): new variable.
1303 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1304 avoid memory leaks when allocating.
1306 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1308 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1311 * gc.c, tags.h: Doc fixes.
1313 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1315 * eval.c (macro-eval!): Removed. This function was a design bug.
1316 It allowed memoized code to leak out to the scheme level. Most
1317 things that you could do with `macro-eval!' can be done with
1320 1997-12-20 Tim Pierce <twp@skepsis.com>
1322 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1323 scm_fgets now depends on ftell(3) to know how many bytes were
1326 1997-12-15 Tim Pierce <twp@skepsis.com>
1328 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1329 dealing with strings.
1331 1997-12-13 Tim Pierce <twp@skepsis.com>
1333 Make %read-line more suitable for implementing read-line efficiently.
1334 * ioext.c (scm_read_line): Strip the terminating newline from a
1335 string, and return a cons of the string and its terminator.
1337 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1338 of the string that is read is stored in this memory location.
1339 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1340 * genio.c, genio.h (scm_do_read_line): Update caller.
1341 * ports.h (scm_ptobfuns): Update typedef.
1342 * fports.c (scm_fptob, scm_pipob): Update struct.
1344 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1346 * filesys.c (set_element): Return file descriptor.
1347 (fill_select_type): Return the highest file descriptor.
1348 (scm_select): Tell select about the highest file descriptor. On
1349 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1350 Therefore the extra overhead for calculating the maximum fd seems
1351 to be more than compensated. Is this correct? In any case,
1352 scm_internal_select will be much faster with this info.
1353 (scm_select, fill_select_type, set_element): Don't accept any kind
1354 of object in the file descriptor list or vector.
1356 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1358 * iselect.c (finalize_fd_sets): Bugfix.
1360 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1362 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1363 when using scm_internal_select (since we might switch to another
1366 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1368 * simpos.c (scm_system): always define: use sysmissing if not
1369 available. Check for HAVE_SYSTEM instead of _Windows (does
1370 Windows lack system or does it have an unusable one?).
1371 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1372 Let the argument be optional: if not supplied, call system(NULL).
1374 * ports.c (scm_close_port): relax the type check from OPPORTP to
1375 PORTP; closing a closed port is allowed.
1377 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1379 * fports.c (scm_fgets): Return if the last char in a chunk is
1380 newline. When fgets returns a string whose length is `size-1', it
1381 is ambiguous whether a whole line was retrieved, so we must check
1382 explicitly whether a line terminator is present.
1384 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1386 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1387 before taking the CDR. (Thanks to Harald Meland.)
1389 * filesys.c (scm_stat): Slightly optimized.
1391 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1393 * ports.c (scm_close_port): Make sure the port is open before
1396 * guile-snarf.in: Pass args through to gcc in a way that preserves
1397 whitespace boundaries. (Thanks to Greg Badros.)
1399 1997-12-02 Tim Pierce <twp@skepsis.com>
1401 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1402 statement. (Thanks to Doug Evans for pointing this out.)
1404 1997-12-01 Tim Pierce <twp@skepsis.com>
1406 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1408 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1410 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1411 errno macro expansion of this field name. (errno is a C
1412 preprocessor macro on some systems.)
1414 1997-11-29 Tim Pierce <twp@skepsis.com>
1416 * iselect.c: Doc fix.
1418 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1420 * init.c (scm_start_stack): Removed initialization of
1421 scm_the_last_stack_var.
1423 * backtrace.h: Declare scm_the_last_stack_var.
1425 * backtrace.c: Define scm_the_last_stack_var.
1427 * root.c (mark_root): Don't mark the_last_stack_var.
1429 * root.h (scm_root_state): Removed the_last_stack_var.
1431 * throw.c: Added #include "fluids.h"
1432 (ss_handler): `the-last-stack' is now a fluid.
1434 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1435 --> the_last_stack_fluid.
1437 * backtrace.c: Added #include "fluids.h"
1438 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1439 (scm_backtrace): `the-last-stack' is now a fluid.
1441 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1442 after scm_init_fluids.
1444 1997-11-28 Tim Pierce <twp@skepsis.com>
1446 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1448 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1449 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1451 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1453 * iselect.c (coop_next_runnable_thread,
1454 coop_wait_for_runnable_thread): Disable interrupts so that no
1455 async is executed before a potential error_revive.
1456 (scm_internal_select): Disable interrupts during the parts of the
1457 code which manipulate the sleep queue and the file descriptors.
1459 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1461 * Makefile.am: Added iselect.c and iselect.h.
1463 * coop.c (coop_qinit): Initialize fields used by
1464 scm_internal_select.
1465 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1466 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1467 replacement in iselect.c.
1468 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1469 coop_join): If GUILE_ISELECT enabled, use
1470 coop_wait_for_runnable_thread instead of
1471 coop_next_runnable_thread.
1472 (usleep, sleep): New replacements for system functions if
1473 GUILE_ISELECT is enabled.
1475 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1477 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1479 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1480 iselect.h. Implement Scheme level `select' using
1481 scm_internal_select. (See NEWS.)
1483 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1485 * init.c: Call scm_init_iselect.
1487 * iselect.h, iselect.c: New files. Implements
1488 scm_internal_select. (See NEWS.)
1490 1997-11-27 Tim Pierce <twp@skepsis.com>
1492 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1493 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1494 and scm_must_free, since ultimately the string returned will be copied
1495 by scm_makfrom0str anyway. Also, read any characters that may have
1496 been pushed onto the port with scm_ungetc.
1497 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1498 * ioext.c (scm_read_line): Free string after Guilifying it.
1499 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1501 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1503 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1505 * gh.h: Safely wrap prototypes for c++ usage.
1507 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1509 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1510 gh_repl (argc, argv).
1512 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1514 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1515 and to invoke scm_shell().
1516 (gh_launch_pad): took out the loading of boot-9.scm from here,
1517 since it is probably best to let the user control that. In fact,
1518 gh_repl() now invokes scm_shell() which does that.
1520 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1522 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1525 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
1527 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
1528 yesterday's underscore patch. (Thanks to Marius Vollmer for
1531 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1533 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if

1539 (gh_uniform_vector_ref): started implementing the uniform types in
1542 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1544 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1545 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1547 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1549 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1550 configure.in was changed).

1554 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1555 * Makefile.in: Regenerated.
1557 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1559 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1560 OPORT is an `open' port, not an output port.
1562 * filesys.c (scm_close, set_element, get_element, scm_chown,
1563 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

1569 scm_close_all_ports_except, scm_set_current_output_port,
1570 scm_set_current_error_port): Likewise
1571 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1572 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1574 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise

1580 * unif.c (scm_uniform_array_write): Likewise
1582 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1584 Minor problems with substring-related tag changes.
1585 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1586 exactly what we want to leave in to detect substrings.
1587 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1588 * tags.h: Fix diagrams and comments describing the S tag bit;
1589 remove vestigial remarks about the D tag bit.
1590 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1591 * strings.c: Formatting tweaks.
1593 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1594 variable first; then SCHEME_LOAD_PATH, with a warning message.
1595 (scm_parse_path): New function.
1596 * script.c: Doc fixes.
1598 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1600 Readline support, from Daniel Risacher.
1601 * readline.c, readline.h: New files.
1602 * init.c: #include "readline.h".
1603 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1604 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1605 * Makefile.in: Regenerated.
1606 * scmconfig.h.in: Regenerated, after change to ../configure.
1608 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1610 * gh.h: gh_vector_set -> gh_vector_set_x
1612 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1614 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1615 with the ! -> _x mapping when going from Scheme to C.
1617 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1619 * gh.h (gh_reverse):
1627 (gh_assoc): added these gh_ functions implemented as macros.
1629 * gh_predicates.c (gh_null_p):
1630 (gh_string_equal_p): added these two missing predicates.
1632 * gh_list.c (gh_append):
1637 (gh_set_cdr_x): added these routines as I go through and try to
1638 complete the picture R4RS functions that should be mirrored in the
1641 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1643 * tags.h (scm_tc7_substring): Changed the comment and code to
1644 conform with the changes below. Folks! We have suddenly two new
1645 free tc7 codes!!! Jummy, jummy!
1647 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1649 * Makefile.in: Rebuilt.
1650 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1652 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
1653 * unif.c (scm_vector_set_length_x): Don't handle multibyte

1670 (scm_tc7_mb_string): Removed.
1671 (scm_tc7_mb_substring): Removed.

1674 Don't include "mbstrings.h".
1675 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1676 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1678 Don't include "mbstrings.h".
1679 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1680 (SCM_SYMBOL_SLOTS): Define as 4.

1702 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1703 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1705 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1707 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1709 * gh_test_c.c (c_vector_test): some improvements on the vector
1712 * gh.h (gh_vector): this used to exist but do the wrong thing.
1713 Now it (almost) does the right thing, though it takes a list
1714 instead of the individual arguments. I need to see how it could
1716 (gh_list_to_vector): added this function as a macro. Corresponds
1717 to Scheme's (list->vector ...).
1718 (gh_vector_to_list): added this function as a macro. Corresponds
1719 to Scheme's (vector->list ...).
1721 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1722 gh_vector_ref, so that it resembles the Scheme routines more.
1723 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1724 resembles the Scheme routines more.
1725 (gh_make_vector): this used to be (stupidly) called gh_vector().
1726 This is the right name, since it does the same thing as the Scheme
1727 (make-vector ...) procedure.
1729 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1731 * ports.h: #include "libguile/print.h"
1733 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1734 Some indentation fixes.
1736 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1737 longer a user field; New field: class_flags.
1739 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1741 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1743 * gh_data.c (gh_bool2scm): new function which replaces
1744 gh_int2scmb(), which is now tagged as obsolete.
1746 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1748 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1749 macros should by convention not test for NIMPness.)
1750 (SCM_COERCE_OPORT): Adjust indentation.
1752 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1753 SCM_NIMP test before SCM_PRINT_STATE_P.
1755 * struct.c, struct.h, gc.c: Renamed:
1756 scm_struct_i_layout --> scm_vtable_index_layout
1757 scm_struct_i_vcell --> scm_vtable_index_vcell
1758 scm_struct_i_vtable --> scm_vtable_index_vtable
1759 scm_struct_i_printer --> scm_vtable_index_printer
1760 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1762 * struct.c (scm_print_struct): Use new printer slot; Default
1763 printing: Also output hex code of vtable so that type identity
1764 will be indicated as well.
1765 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1766 Removed struct_printer_var; Removed struct-vtable-offset;
1767 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1768 vtable-offset-user): New constants.
1770 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1771 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1772 If this slot contains a procedure, use that to print structures of
1773 the type represented by this vtable.
1775 * print.c (scm_iprin1): Don't print arguments of macro
1776 transformers. (They are always: exp env.); Bugfix: Unmemoize
1777 transformer source with correct environment.
1779 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1781 Streamlining of call-with-dynamic-root:
1783 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1784 there is now only one catch.
1785 (cwdr_outer_body): Removed.
1786 (cwdr_handler): New function.
1787 (scm_internal_cwdr): New function to perform the function of cwdr
1788 but take args that are more useful to C code. Also, the handler
1789 is now invoked *outside* of the new dynamic root, like the docs
1790 say. We no longer have to catch absolutely all errors, the caller
1791 is responsible for using a handler that does not throw, if he
1793 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1794 * root.h (scm_internal_cwdr): New prototype.
1796 Even more but risky streamlining:
1798 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1799 allocation of the jumpbuf of a root continuation. The changes
1800 below are controlled by it. They are now deactivated.
1801 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1802 the JMPBUF of the scm_rootcont to NULL before returning.
1804 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1805 when they are non-NULL.
1806 (scm_gc_mark): Likewise, mark only when non-NULL.
1808 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1809 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1811 * gc.c (scm_done_malloc): New function.
1812 gc.h (scm_done_malloc): New prototype.
1814 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1815 (struct scm_print_state) [revealed]: New field.

1821 a certain value is acceptable as a port argument.
1822 (scm_print_state_vtable): New variable.
1823 (scm_free_print_state): Set `revealed' field to false.
1824 (scm_iprin1): Call user supplied closure printer with
1825 scm_printer_apply. Print in the traditional way when there isn't
1826 one or when it returns #f.
1827 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1828 Accept a port/print-state pair in addition to just a port.
1829 (scm_prin1): Don't return the print_state to the pool when it has
1831 (scm_printer_apply): Set `revealed' field of print_state to true.
1832 (scm_init_print): Set scm_print_state_vtable.
1833 (print_state_fluid, print_state_fluid_num): Removed.
1835 * throw.h (scm_handle_by_proc_catching_all): New prototype
1836 throw.c (scm_handle_by_proc_catching_all): New function
1838 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1840 * Makefile.in: Regenerated with automake 1.2c.
1842 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1844 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1845 was looping endlessly.
1847 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1849 * strports.c (scm_eval_string): Don't close the port.
1851 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1852 former returns a nice normal integer. (Thanks to Daniel
1855 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1857 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1858 makefile variable as a build parameter called LIBS. The
1859 build-guile program will use this, for the time being.
1860 * Makefile.in: Regenerated.
1862 Thanks to Shiro Kawai:
1863 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1864 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1867 * Makefile.in: Regenerated with automake 1.2a.
1869 * script.c (scm_compile_shell_switches): If we hit the -c or --
1870 arguments, don't set the car of (command-line) to scm_usage_name,
1871 the prettified name of the guile executable; give it the full
1872 path, the way shells usually handle $0.
1874 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1876 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1877 Scheme-level name `array-map' and renamed `serial-array-map' to
1878 `serial-array-map!'.
1880 * backtrace.c: Introduced exception handlers which now enclose
1881 `display-error' and `display-backtrace' so that error reporting
1882 won't get into infinite loops if an error occurs during displaying
1883 of the error. This can very easily happen with user supplied
1884 print call-back routines.
1886 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1888 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1889 the names `serial-array-map' and `array-map' should be removed.)
1891 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1893 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1894 Added #include "objects.h"
1896 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1897 Add #include "feature.h".
1899 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1900 (modinclude_HEADERS): Added objects.h.
1902 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1903 This test is needed at many places in the code and should be
1904 abstracted. (Motivated by the need of this test in libguiletk.)
1906 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1907 (scm_eval_string), load.c (scm_primitive_load,
1908 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1909 Use SCM_EOF_OBJECT_P.
1911 * eval.c (scm_init_eval): Add feature `delay'.
1913 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1915 * scmhob.h: Removed.
1917 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1919 * list.h (SCM_LISTn): New macros. Make list creation in C code
1920 prettier. The idea comes from STk.
1922 * sequences.h, sequences.c, append.h, append.c: Removed. These
1923 files implemented non-R4RS operations which would encourage
1924 non-portable programming style and less easy-to-read code.
1926 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1929 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1930 sequences.h, #include append.h.
1932 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1935 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1937 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1939 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1941 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1943 * eval.c: Added #include "objects.h"
1945 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1948 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1949 adjacent smob numbers.
1951 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1953 * procprop.h: Added declaration of scm_i_inner_name.
1955 * gsubr.c: New global symbol scm_i_inner_name.
1957 * debug.c (scm_procedure_name): Try procedure property
1958 `inner-name' if `name' fails.
1960 * print.c (scm_iprin1): Use scm_macro_name.
1962 * eval.c (scm_m_define): Give names to macros as well; Only the
1963 first top-level definition gives a procedure/macro a name.
1964 Otherwise confusing names can turn up in backtraces.
1965 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1966 `name'; Give names to macros as well.
1968 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1969 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1972 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1974 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
1976 (prinmacro): Removed. The code has been moved/merged into print.c
1977 in order to decrease code redundancy. We want macros to print in
1978 a way equivalent to procedures, and it would be silly to duplicate
1979 the required code. (We don't want to maintain two places.)
1980 (macrosmob): Print field is now a NULL pointer.
1982 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1983 scm_macro_transformer): New prototypes.
1984 (scm_tc16_macro): Declared.
1986 * print.c (scm_iprin1): Added code for printing of macros. Macros
1987 are now printed in a way equivalent to procedures.
1989 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1991 * procs.h (scm_closure_p): Added declaration.
1993 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1995 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1996 Shouldn't pass "heap" as the subr name.
1998 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
2000 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
2001 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
2002 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
2003 gh_equal_p): Use SCM_NFALSEP, instead of testing against

2008 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
2009 scm_gensym): Added prototypes.

2029 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
2031 * Makefile.in: Regenerated, so it uses "tar", not "gtar".

2044 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
2045 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,

2058 * list.c (scm_list_append_x): Allow non-pair as last argument.
2059 This is consistent with the R4RS append and is probably the
2060 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
2062 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2064 * stime.h: prototype for scm_times.

2082 third argument is now optional.
2084 * posix.c (scm_execl, scm_execlp): make the filename argument
2085 compulsory, since omitting it causes SEGV.
2086 (scm_sync): return unspecified instead of #f.
2087 (scm_execle): new procedure.
2088 (environ_list_to_c): new procedure.
2089 (scm_environ): use environ_list_to_c. disable interrupts.
2090 (scm_convert_exec_args): take pos and subr arguments and
2091 improve error checking.
2093 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2095 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
2096 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2097 argument to SCM_ASSERT. Furthermore, the name of the function
2098 should be passed as first argument when signalling
2099 SCM_WNA. (Thanks to Thomas Morgan)
2101 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2102 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2103 dispatches on the number of actual args has a default case
2104 reporting an internal error. This is a vestige from a version
2105 that mallocated a SCM vector to hold the arguments. In the
2106 current version this check is too late: if it ever happens we will
2107 have already overstepped the bounds of the array.
2109 Also, the patch [...] adds a check for too many actual arguments."
2111 mdj: Removed check for "internal programming error".
2113 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2115 * gh_io.c (gh_write): New function.
2117 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:

2130 fold in the functionality of scm_primitive_dup.
2131 (scm_primitive_dup): deleted.
2133 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2135 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
2136 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
2137 ultrix are defined. Use setvbuf instead of setbuf.
2138 (scm_setvbuf): new procedure.
2139 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
2140 (scm_setfileno): moved from ioext.c.

2152 state as nested data while they are printed.
2153 (print_state_fluid, print_state_fluid_num): New variables.
2154 (scm_init_print): Initialize them.
2155 (scm_iprin): If print_state_fluid carries a print_state, use that
2156 instead of creating a new one.
2157 (scm_printer_apply, apply_stub, struct apply_data): New
2158 definitions to help with calling printer functions written in
2160 * print.h (scm_printer_apply): New prototype.

2173 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
2174 SCM_ASSERT: arg comes before pos.
2176 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2178 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
2179 to a list of length zero correctly.
2181 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

2197 * ioext.h: removed scm_duplicate_port prototype.
2199 * ioext.c (scm_primitive_dup2): return the new file descriptor
2200 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2202 (scm_fdopen): bug fix: don't try to make port unbuffered until its
2203 stream has been set.
2204 (scm_duplicate_port): deleted, there's now an implementation in

2230 * filesys.h: scm_close prototype.
2231 * filesys.c (scm_close): new procedure, can close file descriptors
2232 and ports (scsh compatible).
2234 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an

2257 data. (dynl_smob): Use it.
2258 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2259 the dynamic object data below the linking of the object to avoid
2260 memory leak when the linking code throws an error. Now the code
2261 leaks a whole dynamically linked library when must_malloc throws,
2262 but that should be much less likely.
2264 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2266 Changes to compile under gnu-win32, from Marcus Daniels:

2304 think this is left over from the (eq? '() #f) days.
2306 * read.c (recsexpr): Give this a dummy definition if
2307 DEBUG_EXTENSIONS isn't #defined.
2309 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2311 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

2326 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2328 * simpos.h: prototype for scm_primitive_exit.

2337 turn off REG_EXTENDED.
2338 (scm_init_regex_posix): New regexp/basic symbol.
2339 (REG_BASIC): #define this if it is not already present.

2362 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional

2386 (cwdr_outer_body): New function, to establish the user's handler,
2387 and pass control to cwdr_inner_body.

2399 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2400 the feeling that real thread systems will not need this...
2402 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2404 Try to detect when people are using one version of libguile and a

2416 primitive definitions under their Scheme names.
2418 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2419 1:2. Helps avoid confusion between installed and uninstalled libs.
2421 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2424 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2425 backslash from definition; this should be used like: GDB_INTERFACE;

2429 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2430 new port unbuffered until its stream has been set.
2432 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2434 * ports.h: new prototype.
2435 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.

2444 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2446 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2447 argument plain char *.
2448 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2450 * tag.c (scm_tag): Remove unreachable statement.
2451 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2452 top of the word, it should be unsigned.
2454 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2455 is defined, to avoid warnings; it's only used in the
2456 conflict-checking code. Which might go away anyway.
2457 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2458 conditionals; put the label definition in an #if too, to stifle
2461 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2462 ChangeLog-threads in the distribution.
2463 * Makefile.in: Regenerated.

2467 * guile-snarf.in: Changed regexp to support CPPs that insert
2468 whitespace between lexical tokens (which munges the `%%%' snarf
2471 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2473 * load.c (scm_init_load_path): Append $(datadir)/guile to
2474 %load-path, so modules do not have to be installed in Guile's
2475 current version directory.
2477 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2479 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2480 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2481 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2482 call the sysdep functions with deferred ints.
2483 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2484 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2485 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2488 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2491 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2493 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2495 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2497 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2500 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2502 * eval.c (scm_lookupcar1): New procedure to cope with a race
2503 condition during lookup (when using threads).
2504 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2505 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2508 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2510 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2511 supplied. (Change from Tim Pierce.)
2513 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2515 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2516 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2517 default and not `()'. `#f' is the canonical non-value in Scheme,
2520 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2522 * struct.c (struct_printer): New variable that holds a handle on
2523 the Scheme variable *struct-printer*. This variable can be set by
2524 Scheme code to override the printing of structures.
2525 (scm_print_struct): If struct_printer is set, call it. If it is
2526 not set, or returns #f, print the structure in the old fashion.
2527 Include "eval.h" for scm_apply.
2529 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2531 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2532 scm_struct_i_n_words to get the number of fields, not
2533 -scm_struct_n_extra_words.
2535 On the route to fancier struct printing:
2536 * struct.c (scm_print_struct): New function to print a structure.
2537 Include "genio.h" to support it. This function doesn't do
2538 anything interesting right now, but I think it should be here
2540 * struct.h: Include "print.h" and add prototype for
2542 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2543 print structures ourself.
2545 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2547 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2548 before applying the handler in case it doesn't return.
2550 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2552 * scmsigs.h, async.h: updated.
2554 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2557 * posix.c (scm_uname): interpret only negative values as an error.
2558 Solaris normally returns a positive value.
2560 * script.c (scm_compile_shell_switches): if we are not going into
2561 an interactive repl, set scm_mask_ints to zero so that asyncs can
2564 * simpos.c (scm_system): don't ignore/unignore signals around
2567 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2570 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2571 done in boot-9.scm instead.
2573 * scmsigs.c, async.c: Major rewriting of signal handling code.
2574 (scm_sigaction): new procedure.
2575 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2577 (scm_raise): return unspecified, throw error on failure.
2579 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2581 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2582 feature, to help boot-9.scm decide whether to import the regex
2585 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2587 * eval.c: Include scmconfig.h at the beginning of the file so that
2588 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2591 * regex-posix.c: #include "_scm.h" before conditionally #including
2592 <regex.h>; the former defines HAVE_REGCOMP.
2594 * regex-posix.c: #include <regex.h> conditionally, so the file is
2595 CPP'able (for dependency scanning) even on systems that don't have
2598 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2600 Add new R4RS-compliant syntax for keywords.
2601 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2602 regardless of the setting of the `keywords' read option.
2603 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2604 can be re-read no matter what the setting of the `keywords' read
2607 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2609 Add support for POSIX regular expressions.
2611 * regex-posix.c, regex-posix.h: New files. (Some code
2612 is taken liberally from rx/rgx.c in the old Guile dist.)
2614 * init.c: Include regex-posix.h.
2615 (scm_boot_guile_1): Call scm_init_regex_posix.
2617 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2618 Add regex-posix.[ch] sources.
2619 * Makefile.in: Regenerated.
2621 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2622 to do this automatically? It didn't for me, bleh.)
2624 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2626 * fports.c (print_pipe_port): New function.
2627 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2628 latter doesn't even take the right arguments.
2630 * Makefile.am: Increment shared lib revision number. I think
2631 sometimes the uninstalled Guile finds the installed shared lib;
2632 Gord says doing this might help. As things turned out, I can't
2633 say whether it does.
2634 * Makefile.in: Regenerated.
2636 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2637 passing it as the closure argument to scm_boot_guile. (Bill
2640 * ports.c (print_void_port, putc_void_port, puts_void_port,
2641 write_void_port, flush_void_port, getc_void_port, close_void_port,
2642 noop0): Use ANSI prototypes instead of K&R declarations, so the
2643 initialization of void_port_ptob gets aggressively type-checked.
2644 Fix arguments of print_void_port and write_void_port. (Bill

2678 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2680 * script.c (scm_find_executable): Use prototype-style definition
2681 here; apparently it's not quite right to have const in a prototype
2682 and then use a K&R declaration. I wonder if stuff like this will
2683 go away if we compile with -Wrequire-prototypes, or whatever that
2684 is... (Bernard URBAN)
2686 * scmhob.h: New text from Bernard URBAN.
2688 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2690 * script.c: Don't #define const on hpux. Configure takes care of
2691 this. (Thanks to Larry Schwimmer.)
2693 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2694 decide whether to #include <unistd.h>, instead of listing a bunch
2695 of systems. Don't #include stdio twice. Removed dyked-out
2696 definition of scm_find_impl_file.
2698 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2700 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2701 library version info to 1:0.
2702 * Makefile.in: Regenerated.
2704 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2708 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2709 throw.c: Update copyright years; these files have been worked on
2710 significantly in 1997, but only had copyright years for 1996.
2711 Also, change name of copyright holder on some from Mikael
2712 Djurfeldt to Free Software Foundation; he has signed papers
2713 assigning the changes to the FSF.
2715 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2716 reason not to give the user the option.
2718 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2719 Return #f on end-of-file when scanning table (i.e. when called
2720 with no arguments). Try to catch errors, when we can.
2721 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2723 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2724 external declarations. These are useful.
2726 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2728 * posix.c: don't include <sys/select.h> or define macros for
2729 select, since they were not used in this file.
2731 * filesys.c (scm_select): make the fifth parameter microseconds,
2732 not milliseconds. let the fourth parameter be either a real value
2733 or an integer or #f. The first, second and third arguments can
2734 now be vectors: the type of the corresponding return set will be
2736 (set_element, get_element): new static procedures.
2738 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2740 * strports.c (scm_eval_string): New function.
2741 (scm_eval_0str): Trivially re-implemented in terms of
2743 * strports.h (scm_eval_string): New extern decl.
2745 * net_db.c (h_errno): Add extern decl for this.
2747 * fports.c (local_pclose): New function.
2748 (scm_pipob): Use it in the initializer here.
2751 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2752 Use a meaningful error message when signalling an error. For
2753 this, scm_gethost must check h_errno rather than errno.
2755 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2757 * Makefile.in: Regenerated, using automake-1.1p.
2759 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2761 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2762 not SCM_UNSPECIFIED.
2764 * script.c (scm_compile_shell_switches): don't append (quit) if
2766 (scm_shell): call scm_exit_status and exit on the result of the
2769 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2771 Ensure that shared substrings are handled properly when passed to
2772 a system call or other foreign function. Many thanks to Tim
2774 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2775 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2776 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2777 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2779 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2780 (scm_display_error_message): use RO macros when strings may be RO.
2781 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2782 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2783 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

2788 scm_strftime), vports.c (scm_make_soft_port): use
2789 SCM_COERCE_SUBSTR to make sure shared substrings are
2792 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2794 * error.c (scm_error): Add newline to error message.
2796 * init.c (scm_init_standard_ports): Doc fix.
2798 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2800 * dynl-shl.c: Completely replaced with new code from Bernard
2803 * script.c (scm_ice_9_already_loaded): New variable.
2804 (scm_compile_shell_switches): Use it.
2806 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2808 * filesys.c (scm_input_waiting_p): add missing third argument to
2811 * stime.c (scm_localtime): copy the result of localtime before
2812 calling gmtime in case they share a buffer.
2813 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2816 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2818 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2820 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2822 * Makefile.am (check-local): New target, which causes 'make check'
2823 to run gh_test_c and gh_test_repl, with some trivial input.
2824 * Makefile.in: Rgnrtd.
2826 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2828 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2831 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2833 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2834 sure how this was supposed to work.
2835 (scm_async_click): don't send SCM_TICK_SIGNAL.
2836 (scm_init_async): don't initialize %tick-thunk.
2838 * the following change doesn't affect the Scheme interface:
2839 gc-thunk is called at the end of garbage collection. however it's
2840 no longer implemented by pretending it's a signal.
2842 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2843 system async corresponding to scm_gc_thunk.
2844 * async.h: declare scm_gc_async.
2845 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2846 gc-thunk directly, instead of going through a signal handler.
2847 (scm_gc_async): new variable, points to the GC system-async.
2848 (scm_init_async): save the GC async as scm_gc_async instead
2849 of using system_signal_asyncs.
2850 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2852 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2854 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2855 Don't screw up if we're interrupted.
2856 * Makefile.in: Regeneradet.
2858 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2860 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2862 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2863 we're not using AM_INIT_GUILE_MODULE any more.
2864 * Makefile.in: Reneregated.
2866 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2868 Functions for finding variable bindings, grace à Tim Pierce.
2869 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2870 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2872 Get 'make dist' to work again.
2873 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2874 * Makefile.in: Regenerated, like a surry without a fringe on top.
2876 Changes for reduced Guile distribution: one configure script,
2878 * configure.in, configure: Removed.
2879 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2880 real configure script lives.
2881 * Makefile.in, scmconfig.h.in: Regenerated.
2883 * init.c: #include "script.h", to get prototype for script.c's
2886 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2888 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2889 scm_must_malloc, not raw malloc.
2891 * script.c (scm_compile_shell_switches): Dyke out debugging output
2894 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2896 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2898 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2899 system has them. Hope this is safe. Previously
2900 sys/timeb.h was included if HAVE_FTIME was defined or if
2901 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2902 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2904 * ioext.c (scm_setfileno): add missing third argument to
2905 scm_misc_error call.
2907 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2909 * eq.c (scm_equal_p): Correctly compare strings of different
2910 varieties. (Thanks to Tim Pierce.)
2912 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2914 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2915 #! block comment must occur on a line all by itself.
2917 Move most of the guts of shell command processing into libguile,
2918 so guile.c can be very small (and eventuallly auto-generated. (I
2919 mean, generated mechanically, not self-generated. Hmm.))
2920 * guile.c, script.c, script.h: New source files.
2921 * init.c (scm_boot_guile_1): Call scm_init_script.
2922 * libguile.h: #include "script.h".
2923 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2924 targets, for new executable.
2925 (libguile_la_SOURCES): Mention script.c.
2926 (modinclude_HEADERS): Add script.h.
2927 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2928 not dynamic linking is enabled. This is because we're generating
2929 executables now. Move CY_AC_WITH_THREADS call after those, so the
2930 values of cy_cv_threads_libs captures the libs chosen above.
2931 * Makefile.in, configure, aclocal.m4: Regenerated.
2933 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2934 We don't maintain this interface any more, and it just confuses
2937 * alloca.c: #include <scmconfig.h>, not <config.h>.
2938 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2939 it'll get included in disties.
2941 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2943 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2944 be distributed, because they confuse people.

2954 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2956 * backtrace.c (scm_backtrace): Split message string across
2957 newlines properly. GCC is more tolerant of this than other

2970 coop-threads.c.cygnus, coop-threads.h.cygnus.
2971 * configure.in: If we're using threads, include threads.o in
2973 * _scm.h, libguile.h: threads.h lives in this directory now.
2974 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2975 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2976 currently used, but brought along for information's sake.
2977 * ChangeLog-threads: log from old 'threads' directory.
2978 * Makefile.in, configure: Rebuilt.
2980 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2982 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2985 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2987 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2989 Merge GH interface library into libguile.

2992 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2993 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2995 (EXTRA_libguile_la_SOURCES): ... here.
2996 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2997 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2998 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2999 New variables, describing how to build the gh test programs.
3000 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
3001 build the test programs, and we probably should have been linking
3002 libguile.la against them all along, to support AIX shared libs.
3003 Add cflags for threads to CFLAGS; add libs for threads to new
3004 variable THREAD_LIBS, used in Makefile.am.
3005 * ChangeLog-gh: log from old `gh' subdirectory.
3006 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
3008 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
3010 * acconfig.h: Undo change of Apr 9; including the definition of
3011 PACKAGE in the guile headers conflicts with applications' own
3013 * scmconfig.h.in: Regenerated.
3015 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

3024 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
3026 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
3027 have S_IFSOCK. This is the case under Ultrix.
3029 * posix.c (scm_status_exit_val, scm_status_exit_val,
3030 scm_status_term_sig, scm_status_stop_sig): Modified to work with
3031 Ultrix versions of WIFSTOPPED, etc., which assume that their
3032 arguments are lvalues (hmm).
3034 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3036 * eval.c: Doc fixes.
3038 * throw.c: Doc fixes; rearranged.
3040 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
3042 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
3044 * acconfig.h: Added entry for PACKAGE.
3045 * scmconfig.h.in: Regenerated.
3047 Changes to work with automake-1.1n, which has better libtool support.
3048 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
3049 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
3051 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
3053 * Makefile.in: Rebuild.
3055 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3057 * stime.c (scm_mktime): take an optional zone argument.
3058 (scm_localtime): check putenv return value.
3059 (scm_strftime, scm_strptime): moved from posix.c. move #include
3061 stime.h, posix.h: update prototypes.
3062 (bdtime2c, setzone, restorezone): new static procedures.
3063 (scm_mktime, scm_strftime): use them.
3064 (scm_strftime): don't call mktime before strftime. Use
3065 filltime for return value.
3066 (filltime): convert NULL zname to #f.
3067 (scm_strptime): return a count of characters consumed, not
3068 the remaining string.
3070 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3072 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

3075 Uncomment localtime and mktime.
3077 * configure.in: add AC_STRUCT_TIMEZONE.
3079 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3081 * stime.c (scm_init_stime): don't define ticks/sec.
3082 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
3083 return value problem and is still portable.)
3085 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3087 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
3088 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
3089 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
3090 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3091 cpp_err_symbols.c): Corresponding changes.
3092 * Makefile.in: Regenerated.
3094 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3096 * posix.c (scm_putenv): don't check HAVE_PUTENV.
3097 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
3098 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
3099 * putenv.c: new file, from sh-utils 1.12.
3101 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3102 since allocation isn't for Scheme objects.
3103 (scm_putenv): copy strings before placing in the environment.
3105 * stime.c (scm_current_time): throw an error if time returns -1,
3106 instead of returning #f.
3107 (scm_get_internal_real_time, scm_get_internal_real_time): use
3108 scm_long2num for return value instead of SCM_MAKINUM.
3110 * stime.h: prototypes updated.
3112 * stime.c (scm_time_in_msec): apparently unused, deleted.
3114 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3116 * configure.in: check for gettimeofday.
3118 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3119 which may be more usefully portable than a gettimeofday interface.
3121 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3123 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
3125 * Makefile.in: Regenerated.
3127 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3129 * stime.c (filltime): recovered static procedure.
3130 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
3133 * posix.h: add prototype for scm_close_pipe, remove prototypes for
3134 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3136 * posix.c (scm_mknod): split the mode argument into type and perms
3137 arguments, like the extra fields returned by stat.
3139 * fports.c (scm_pipob): set the close, free and print procedures.
3140 (scm_close_pipe): new procedure.
3142 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3143 define them in boot-9.scm
3145 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3147 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3148 wan't defined. Don't include fd.h.
3150 * Previously fd.h was regenerated whenever configure was run,
3151 forcing a couple of files to be recompiled.
3153 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3154 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3155 Check for _fileno as well as _file.
3157 * ioext.c: don't fd.h.
3158 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3161 * Change the stratigy for getting information about errno
3162 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3163 generating lists of symbols during the build process, which will
3164 not always work, include comprehensive lists in the distribution.
3165 To help keep the lists up to date, the "check_signals" and
3166 "check_errnos" make targets can be used.
3168 * configure.in: don't check for a command to extract errno codes.
3169 * Makefile.am: update file lists, remove errnos.list and errnos.c
3170 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3171 check_errnos targets.
3172 (CLEANFILES): remove errnos.c and errnos.list, add
3173 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3174 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3175 * errnos.default: deleted.
3176 * cpp_signal.c: new file.
3177 * cpp_errno.c: renamed from errnos_get.c.
3178 * cpp_err_symbols, cpp_sig_symbols: new files.
3179 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3180 * error.c (scm_init_error): #include cpp_err_symbols instead of
3182 * posix.c (scm_init_posix): don't intern signal symbols. #include
3185 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3187 * strop.c (scm_i_index): allow the lower bound to be equal to the
3188 length of the string, so a null string doesn't always give an error.
3190 * posix.h: new prototypes.
3191 * posix.c (scm_status_exit_val, scm_status_term_sig,
3192 scm_status_stop_sig): new functions, as in scsh. They break down
3193 process status values as returned by waitpid.
3195 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3197 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3198 configure doesn't know about it.
3200 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3202 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3204 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3205 which defines C variables with global linkage.
3207 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3209 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3212 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3214 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3215 has time to check why this doesn't work well with continuations.
3217 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3219 * Fix shell syntax error; some shells won't tolerate
3220 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3222 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3224 * posix.c (scm_uname): throw an error if uname fails instead
3227 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3229 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
3232 * async.c (scm_ints_disabled): definition moved from error.c.
3234 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3236 * acconfig.h: Removed PACKAGE.
3238 * scmconfig.h.in: Regenerated.
3240 * snarf.h: g++ says it's non-portable not to specify the first
3241 argument in a varargs declaration. I introduced the first
3242 argument by using preprocessor conditionals.
3244 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3246 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3247 (scm_freopen): use RO string macros for filename and modes.
3248 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3250 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3251 (scm_mknod): use RO string macros for path.
3253 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3254 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3256 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3257 use SCM_ROSTRINGP and SCM_ROCHARS.
3259 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3261 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3264 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3265 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3266 support for byte vectors.
3268 * print.c (scm_iprin1): Limit number of vector elements printed
3269 according to pstate->length.
3271 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3273 * backtrace.c (scm_display_error_message): don't segv if message
3276 * error.h: prototype for scm_error_scm.
3278 * error.c (scm_error_scm): new procedure, reimplements scm-error
3279 in C and uses scm_error.
3281 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3283 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3284 pointer to the Scheme variable read-hash-procedures and intern it
3285 in scm_init_read. Modify scm_read_hash_extend and
3286 scm_get_hash_procedure to use the pointer.
3288 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3290 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3291 (SCM_KEYWORD_STYLE): defined.
3293 * read.c (scm_read_opts): add a keywords option. This isn't a
3294 boolean option, in case someone wants to add support for DSSSL
3296 Setup scm_keyword_prefix symbol.
3297 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3299 I've left keyword support disabled by default, since it doesn't
3300 seem to break the module system and it gives R4RS standard behaviour.
3301 It can be reactivated with (read-set! keywords 'prefix).
3303 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3305 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3306 before constructing arbiter.
3308 * eval.c (scm_m_define): Bugfix: Check that the object is a
3309 closure before setting the procedure property!
3311 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3313 * ports.c: Removed `ungetc-char-ready?'.
3315 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3317 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3318 (idea from Mikael: make it a pair so scm_permanent object only
3320 (scm_read_hash_extend): don't call scm_permanent_object.
3321 (ideas from Mikael): if chr is already in the list, replace its
3322 procedure instead of appending it again. If proc is #f, remove
3324 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3326 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3328 * gdbint.c (gdb_read): update scm_lreadr usage.
3330 * load.h: update prototypes.
3332 * load.c (scm_primitive_load, scm_read_and_eval_x,
3333 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3335 * read.h: add prototype for scm_read_hash_extend. Change args for
3338 * read.c (scm_read_hash_procedures): new variable.
3339 (scm_read_hash_extend): new procedure.
3340 (scm_get_hash_procedure): new procedure.
3341 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3342 for extended # processing.
3343 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3344 scm_read_token): remove case_i, sharp arguments. Change callers.
3346 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3348 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3349 (SCM_CASE_INSENSITIVE_P): define.
3351 * read.c: add case-insensitive option to scm_read_opts.
3352 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3353 to determine whether to convert symbol case.
3354 (default_case_i): definition removed.
3355 * read.c (scm_read_token): if case_i, downcase ic before doing
3358 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3360 * configure.in: Added configuration option `guile-debug'.
3361 Configure with --enable-guile-debug if you want a bunch of extra
3362 functions used for debugging when developing Guile.
3364 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3366 * procs.c (make-cclo): New undocumented debugging procedure: Make
3367 compiled closure with internal procedure PROC and length LENGTH.
3368 Only compiled if GUILE_DEBUG is defined.
3370 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3372 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3374 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3376 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3377 with 3 or more args internally to the evaluator.
3379 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3381 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3382 with 3 or more args internally to the evaluator. This is mainly
3383 because we don't want to pass entry and exit points of the
3384 debug support twice, but it also seems to increase the speed of
3385 the evaluator for such calls (e. g. (+ 1 2 3)).
3387 * backtrace.c (scm_display_application): New procedure:
3388 display-application; Set fancy printing parameters individually
3389 for different types of display (backtrace, error, application).
3390 (These should of course be customizable!)
3392 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3393 clear the CHECK-flags.
3395 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3397 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3399 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3401 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3402 from pairs with a GLOC in the car.
3404 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3405 otherwise `symbol-hash' will behave badly.
3406 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3407 we get segmentation fault!
3409 * symbols.c: Added #include "weaks.h". New functions:
3410 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3411 moved to an extraneous library when we split libguile.)
3413 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3415 * filesys.c (scm_stat): stat now takes fport arguments too as
3416 documented in the manual.
3418 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3420 * debug.c (scm_single_step): Bugfix: Call continuation with
3421 scm_call_continuation instead of throwing to it.
3423 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3425 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3426 argument wasn't declared to be optional.
3428 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3430 * stime.c (scm_init_stime): Add feature "current-time".
3432 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3434 * throw.h: prototype for scm_exit_status.
3435 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3436 args to derive an exit status. Allows (quit) to work from a
3438 (scm_exit_status): new function.
3441 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3443 * eval.c (scm_deval): Removed some old code.
3444 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3446 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3449 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3452 * procs.c: Introduce the existent C function scm_thunk_p at the
3453 Scheme level as well.
3455 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3457 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3458 used from C to easily lookup the value of a symbol in the current
3461 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3463 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3464 scm_init_unif in this file. This will also fix a previous problem
3467 * configure.in: Added AM_MAINTAINER_MODE
3469 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3471 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3474 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3476 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3477 source files that are not always included in libguile but should
3478 have their dependencies calculated by automake. This variable is
3479 recognized by automake, no further magic is needed.
3480 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3481 to deal exclusively with *.lo files, as it seems. The *.o files
3482 are built automatically when the corresponding *.lo file gets
3485 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3487 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3490 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3492 * unif.c (scm_array_set_x): minor change to argument error checking.
3494 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3496 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3497 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3498 They should only be included in the library at configure.in's
3500 (libguile_la_LDADD): Include the appropriate .lo files here.
3501 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3502 so we know when to build them (and their .lo bretheren).
3503 * configure.in (LIBLOBJS): New substituted variable. We let
3504 configure decide which .o files to include in LIBOBJS, and then
3505 put the corresponding list of .lo files in LIBLOBJS. The latter
3506 is what we pass to libtool.
3507 * Makefile.in, configure: regenerated.
3509 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3511 * symbols.c (scm_sysintern0): New function. Contains the core of
3512 old scm_sysintern but doesn't take a second value argument.
3513 (scm_sysintern): Now uses scm_sysintern0.
3514 (scm_sysintern_no_module_lookup): Renamed to
3515 scm_sysintern0_no_module_lookup and doesn't take a second value
3516 argument any longer.
3518 * symbols.h (scm_sysintern0: Added declaration.
3520 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3521 scm_sysintern when interning option keys. Otherwise we risk
3522 destroying the values of already interned variables.
3524 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3525 scheme-level boolean (use SCM_NFALSEP).
3527 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3529 (scm_backtrace): New function. (C version of old function from
3530 boot-9.scm) Motivation: Make it possible to display backtraces
3531 without depending on boot-9.scm. (I'm uncertain if this
3532 motivation is good enough...)
3534 * root.h (scm_root_state): Add member the_last_stack_var.
3535 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3537 * root.c (mark_root): Mark scm_the_last_stack_var.
3539 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3542 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3544 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3545 1. mark_lazy_catch didn't mark the smob.
3546 2. Both functions above have standard variants:
3547 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3548 free_lazy_catch --> scm_free0.
3550 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3552 * throw.c (scm_internal_lazy_catch): New function.
3553 (scm_lazy_catch): Rewritten to use it.
3554 (scm_ithrow): Handle the new lazy catch representation.
3555 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3556 that doesn't have a jmpbuf is a lazy catch clause.
3557 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3558 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3559 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3561 (scm_init_throw): Register the new lazy-catch smob type.
3562 * throw.h (scm_internal_lazy_catch): decl for new function.
3564 * throw.c (scm_internal_catch): Doc fixes.
3566 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3567 configure.in. Including this might cause problems if applications
3568 that link against libguile include their own copies of alloca, but
3569 if they're using autoconf, they should be adding libguile to LIBS
3570 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3571 the copy in libguile, and things will be okay. (I think.)
3573 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3575 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3577 strop.h: move prototypes too.
3579 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3581 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3584 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3585 etc. I deleted them from filesys.c long ago, but didn't
3586 notice they were here too (although ineffective since
3587 sys/stat.h wasn't included).
3589 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3591 * eval.c: Don't define alloca in GCC case. gcc will automatically
3592 use __builtin_alloca if appropriate.
3594 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3596 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3597 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3598 that values of automatic variables are preserved. See comments
3599 for safe_setjmp for details.
3601 Change from Thomas Morgan:
3602 * variable.c: Include eq.h.
3603 (var_equal): New function.
3604 (variable_smob): Use var_equal as the discriminator for variables.
3606 * throw.c (s_throw): Remove extraneous declaration.
3608 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3609 * eval.c: Add necessary CPP cruft to support that.
3610 * configure, Makefile.in, scmconfig.h.in: regenerated.
3612 Change from Thomas Morgan:
3613 * procprop.c (scm_procedure_properties): Convert the Scheme
3614 boolean returned by scm_procedure_p into a C boolean before using
3615 it as a condition for SCM_ASSERT.
3616 (scm_procedure_property): Likewise.
3618 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3619 indications of Unixness.
3622 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3624 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3626 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3628 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3629 "unknown # object" error messages.
3631 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3632 (scm_i_index) and declare it static. Add a 'direction' argument
3633 to indicate what way the search should go.
3634 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3636 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3637 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3639 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3641 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3643 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3644 to avoid clash with various scsh forks.
3646 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3648 The following two changes (ramap.c, throw.c) are motivated by the
3649 apparent unportability of forward declarations of static arrays of
3650 the form `static foo bar[];'.
3652 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3653 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3655 * throw.c (scm_throw): Moved above scm_ithrow.
3657 * options.h: Removed the extern declarations of scm_yes_sym and
3658 scm_no_sym since these are static.
3660 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3662 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3664 * Makefile.am: remove AWK=@AWK@.
3665 Add a rule for generating errnos.list.
3666 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3668 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3669 don't extract errnos, just set a variable (avoids the
3670 need to recompile error.c just because configure is run.)
3672 * unif.h: update prototypes.
3673 * unif.c (scm_uniform_array_read,write): change the offset and
3674 length arguments to start and end, for consistency.
3676 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3678 * ioext.h: update prototypes.
3679 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3680 scm_read_line_x, it's a more general procedure using an
3681 interface from scsh. read-line and read-line! are now defined
3683 Note that the new read-line trims the terminator
3684 by default, previously it was appended to the returned string. An
3685 optional argument specifies how to process the terminator (scsh
3686 compatible). For the old behaviour: (read-line port 'concat).
3687 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3688 returns a pair, but is converted to multiple values if the scsh
3691 socket.h: update prototypes.
3692 * socket.c (scm_recvfrom): for consistency with other procedures,
3693 take start and end as separate optional arguments.
3694 (scm_recv, scm_recvfrom): don't allow the second argument
3695 to be a size, only a buffer. Change the scheme names to
3696 recv! and recvfrom!. Don't return the buffer.
3698 * ioext.h, posix.h: move prototypes too.
3699 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3700 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3701 "read.h" and "unif.h".
3702 * ioext.c: include "chars.h"
3704 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3706 * dynl.c: The dynamic linking and module registration functions
3707 are now defined even when dynamic linking is not available for the
3708 host system. Some of their functionality can be done without
3709 dynamic linking; when it's really needed, they throw errors.
3711 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3713 * configure.in: Only define DYNAMIC_LINKING when one of the system
3714 dependent functions is detected.
3715 * dynl.c (scm_dynamic_func): New function to get the address of a
3716 function in a dynamic object.
3717 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3718 produced by scm_dynamic_func as the thing to call.
3720 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3722 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3723 (scm_register_module_xxx, scm_registered_modules,
3724 scm_clear_registered_modules): New functions.
3726 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3728 * symbols.c (scm_sysintern): Renamed to
3729 scm_sysintern_no_module_lookup.
3730 (scm_sysintern): New function to take the place of the old
3731 scm_sysintern. It uses the current toplevel lookup closure to give
3732 the symbol its value. This is a temporary hack to put packages
3733 like gtcltk into their own module.
3734 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3735 us whether `scm_top_level_lookup_closure_var' has been initialized
3737 * eval.c (scm_init_eval): Set it.
3739 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3741 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3742 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3744 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3746 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3747 scm_sys_dup): deleted: FD capability will be added to other
3749 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3750 scm_fd_free, fd_smob, scm_intern_fd.
3751 (scm_open): renamed from scm_sys_open. Return a port instead of
3752 an FD object. Make the mode argument optional.
3753 (scm_sys_create): deleted, it's just a special case of open.
3754 (scm_init_filesys): move interning of constants O_CREAT etc.,
3755 here (were previously using SCM_CONST_LONG macro).
3756 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3758 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3759 include "fports.h" and <stdio.h>
3760 (scm_stat, scm_select): don't support FD objects.
3762 * error.h: adjust scm_syserror_msg prototype.
3763 * error.c (scm_syserror_msg): take an extra argument for errno.
3764 Using the global value didn't always work, since it could be
3765 reset by procedure calls in the message or args arguments.
3767 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3768 I don't understand why the check was there (and what about the
3771 * strop.c (scm_string_copy): allow shared substrings to be copied.
3773 * unif.h: corresponding change to prototypes.
3774 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3775 recognize two new optional arguments: offset and length. Allow
3776 the port argument to be an integer (file descriptor, for scsh).
3777 Include <unistd.h> for "read" prototype.
3779 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3781 * socket.c: don't include filesys.h.
3783 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3785 * Makefile.am: add AWK=@AWK@ (?)
3787 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3789 Add a rule to generate errnos.c from errnos.
3790 * error.c (scm_init_error): include errnos.c.
3791 * errnos_cnvt.awk: new file, converts the list of errno codes to
3793 * errnos_get.c: new file.
3794 * errnos.default: new file, contains errnos to try if they can't
3795 be extracted from errno.h.
3796 * configure.in: if using GCC, try and extract errno codes from
3800 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3802 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3803 * Makefile.am: Made libguile into a libtool library.
3804 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3805 Set libtool_libs to indicate that libguile is a libtool library.
3806 See guile/ChangeLog for details.
3807 * .cvsignore: ignore "*.lo", the libtool library objects.
3809 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3811 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3812 use htons in getservbyport argument.
3814 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3816 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3817 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3820 * objprop.c (scm_object_property): No need to take the CDR of the
3821 value returned by scm_object_properties, since Aug 20 change.
3823 * configure.in: When checking for struct linger, #include
3824 <sys/types.h> as well as <sys/socket.h>. I've never known
3825 <sys/types.h> to cause any portability problems, and Solaris's
3826 <sys/socket.h> needs it.
3827 * configure: Rebuilt.
3829 I think the Sun compiler has chosen a perverse way to interpret
3830 ANSI declarations combined with K&R definitions. We'll
3831 appease it a little bit. But when it invades France, we fight.
3832 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3833 * print.h (scm_iprlist): Here too.
3834 * numbers.c (scm_divbigdig): Change definition to match
3835 declaration in numbers.h.
3836 * unif.c (scm_makflo): Change definition to match declaration in
3839 * init.c (scm_boot_guile): Don't return the value of
3840 scm_boot_guile_1. This function doesn't return a value;
3841 scm_boot_guile_1 doesn't return a value (or return at all).
3843 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3846 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3847 compile. I have a feeling this function is a bad idea anyway ---
3848 one should always test for features, not systems.
3850 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3851 semicolons. Only pure luck kept this from being noticed earlier.
3853 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3855 * socket.c (scm_recvfrom): Added missing semicolon.
3857 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3859 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3860 the buffer and start and end positions for scsh networking
3863 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3865 * configure.in: Revert previous change to this file; the problem
3866 is due to transient automake weirdness.
3867 * configure: Rebuilt.
3869 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3870 PLUGIN/guile.libs. configure generates the latter from the former.
3871 * Makefile.in: Rebuilt.
3873 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3874 need this if we install scripts, like guile-snarf.
3875 * configure: Rebuilt.
3877 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3879 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3881 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3883 * socket.c (scm_addr_vector): fix faulty scm_listify.
3885 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3887 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3888 style block comment is no longer considered an error.
3890 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3892 * PLUGIN/guile.libs.in: New file.
3893 * PLUGIN/guile.libs: Removed from repository.
3894 * configure.in: Create PLUGIN/guile.libs from
3895 PLUGIN/guile.libs.in. This is for including additonal libraries
3896 needed for dynamic linking.
3897 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3898 instead of PLUGIN/guile.libs.
3900 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3902 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3904 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3905 occurrences of the given element from the list, not just the
3906 first. This is how the Emacs Lisp functions behave, how the
3907 analogous Common Lisp functions behave, and (I believe) how the
3908 older Maclisp functions worked. I realize that this change may
3909 break code, but it seemed better to break it before the Guile
3912 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3913 Their prototypes were already present in gc.h, but they weren't
3915 (scm_init_storage): Initialize scm_protects.
3916 * root.c (scm_protects): New element of scm_sys_protects.
3918 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3920 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3922 * libguile.h: Added #include "libguile/net_db.h".
3924 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3925 30 change. That file is only meant for communication between the
3926 configuration process and load.c. If code linked against libguile
3927 wants to get at the paths mentioned in libpath.h, it can call
3928 functions declared in load.h.
3930 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3932 * libguile.h: Removed #include "libguile/fdsocket.h"
3934 * net_db.c: Added #include <sys/socket.h>.
3936 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3938 * filesys.c (scm_input_waiting_p): use select in preference to
3939 FIONREAD, since the latter doesn't detect EOF.
3940 Throw error if neither select nor FIONREAD available.
3942 * socket.c (scm_connect): take a port, not a fd object.
3943 (scm_fill_sockaddr): throw an error if fam is not recognised.
3944 (scm_bind): use scm_fill_sockaddr.
3945 (scm_listen): take a port, not a fd object.
3946 (scm_accept): take and return a port. return #f in the car if
3947 address can't be got
3948 (scm_sock_fd_to_port): new procedure.
3949 (scm_socket): use scm_sock_fd_to_port.
3950 (scm_addr_vector): throw error if unrecognised address type.
3951 take an extra argument with the calling procedure name.
3952 (scm_getsockname): take a port. return #f if address can't be got.
3953 (scm_getpeername): take a port. return #f if address can't be got.
3954 (scm_recvfrom): take a port. return #f for address component if can't
3956 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3957 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3959 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3961 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3962 use separate data pointers, to allow them to be designed
3963 independently and reused.
3964 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3965 Renamed from catch_body, catch_handler, and uncaught_throw; made
3967 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3969 (scm_catch): Use the above.
3970 (scm_throw): Don't bother printing a message for an uncaught
3971 throw; we establish a default handler in init.
3972 * throw.h (scm_internal_catch): Prototype updated.
3973 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3975 (struct scm_body_thunk_data): New structure, used as data
3976 argument to scm_body_thunk.
3977 * init.c (struct main_func_closure): New structure, packaging up
3978 the data to pass to the user's main function.
3979 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3980 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3981 scm_internal_catch to establish a catch-all handler, using
3982 scm_handle_by_message. This replaces the special-case code in
3984 (invoke_main_func): Body function for scm_internal_catch; invoke
3985 the user's main function, using the main_func_closure pointer to
3986 decide what to pass it.
3987 * root.c (struct cwdr_body_data): Remove handler_proc member.
3988 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3989 (cwdr_handler): Removed.
3991 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3993 * socket.h (SCM_P): update bind prototype.
3994 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3995 include "feature.h".
3996 (scm_socket): return a port, not a file descriptor object.
3997 include "fports.h" and <unistd.h>
3998 (scm_bind): take a port, not a file descriptor object.
3999 take an extra argument for address args.
4001 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
4002 INADDR_NONE, INADDR_LOOPBACK.
4004 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4006 * init.c: include net_db.h and not fdsocket.h.
4007 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
4009 * Makefile.am: corresponding changes.
4010 * socket.h: renamed from fdsocket.h, fix names.
4011 * net_db.h: renamed from socket.h, fix names.
4012 * socket.c: renamed from fdsocket.c.
4013 remove _sys from procedure names.
4014 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
4015 add "socket" to features list.
4016 * net_db.c: renamed from socket.c.
4017 remove _sys from procedure names.
4018 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
4019 add "net-db" to features list.
4020 include "net_db.h". don't include <sys/socket.h> or
4023 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4025 * tags.h (scm_tags): Removed comma at end of last enumerator.
4027 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
4029 Don't use GCC extensions to allocate space for debugging frames.
4030 (Here he goes again! Why do we put up with this?!)
4031 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
4032 an scm_debug_info structure, not an in-line array of them. Add
4033 'info' member, to say how many vect elements we've used, for eval
4035 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
4036 a new variable debug_info_end to mark the end of vect, instead of
4037 the address of the 'info' pointer itself.
4038 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
4039 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
4040 (SCM_APPLY): Explicitly allocate space for debug.vect.
4041 * debug.c (scm_m_start_stack): Same, for vframe.vect.
4042 * stacks.c: Adjusted for new debug frame structure.
4043 (RELOC_INFO, RELOC_FRAME): New macros.
4044 (stack_depth, read_frames): Use them, and new scm_debug_frame
4045 element 'info', instead of magically knowing that eval frames have
4046 an info pointer sitting after vect.
4047 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
4049 (scm_init_stacks): Formatting tweaks.
4051 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
4053 Give GCC more control flow information, so it can be sure that
4054 variables aren't used uninitialized.
4055 * error.h (scm_error, scm_syserror, scm_syserror_msg,
4056 scm_sysmissing, scm_num_overflow, scm_out_of_range,
4057 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
4058 scm_misc_error): Tell GCC that these functions never return.
4059 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
4060 out the field type, call abort if SCM_ASSERT returns, to placate
4062 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
4063 scm_wta ever returns. We can't handle this case anyway, and this
4064 gives the optimizer more information.
4065 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
4066 scm_wta ever returns.
4068 In some cases, the code is fine, but GCC isn't smart enough to
4069 figure that out; this usually happens when one variable is only
4070 initialized and used when a particular condition holds true, and
4071 we know that condition will never change within a given invocation
4072 of the function. In this case, we simply initialize the variables
4073 to placate the compiler, hopefully to a value which will cause a
4074 crash if it is ever actually used.
4075 * print.c (scm_iprin1): Initialize mw_pos.
4076 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
4077 * throw.c (scm_ithrow): Initialize dynpair.
4078 * unif.c (scm_uniform_vector_ref): Initialize cra.
4079 * struct.c (init_struct): Initialize prot.
4080 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
4082 * strports.c (scm_eval_0str): Don't return uninitialized garbage
4083 if EXPR contains no expressions.
4085 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4087 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
4088 cause an infinite loop (???). So much for the algebraic
4089 equivalency of variable-sized arrays and alloca...
4091 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4093 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4094 a SCM boolean, not a C boolean.
4096 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4098 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4099 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4100 rules for raising scm_mtrigger. Previously, unfortunate but not
4101 unlikely circumstances could result in almost constant invokation
4102 of the gc. Now, this situations should be less likely, but they
4103 are not prevented completely.
4105 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4107 * numbers.c (scm_fuck): Procedure removed; looks like old test
4109 * numbers.h: Prototype removed.
4111 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4113 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4114 array to a pointer, to match my Nov 21 change in eval.c.
4116 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4118 * libguile.h: Added #include "libguile/backtrace.h", #include
4119 "libguile/stacks.h".
4121 * strings.c (scm_string scm_make_string scm_string_ref
4122 scm_string_set_x scm_string_equal_p scm_string_append):
4123 Bugfix according to scm patch from Aubrey Jaffer:
4124 Corrected long-standing
4125 (not (eqv? (integer->char 128)
4126 (string-ref (make-string 1 (integer->char 128)) 0)))
4127 bug found by John Kozak <jk@noontide.demon.co.uk>.
4129 * strports.c, strports.h: Make scm_eval_0str return the value of
4130 the last expression evaluated (previously, it returned void).
4132 * strports.c, strports.h: New function: scm_read_0str. Does what
4135 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4137 * simpos.c (scm_getenv): return #f if string can't be found in the
4138 environment instead of throwing an exception, for compatibility
4139 with numerous other systems.
4141 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4143 * Makefile.am (.c.x): Use guile-snarf.
4144 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4146 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4148 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4150 * backtrace.c (scm_display_error_message): Made non-static, and
4151 renamed from display_error_message.
4152 * backtrace.h (scm_display_error_message): Added extern decl.
4153 * throw.c (uncaught_throw): Use it to display the error message.
4155 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4157 * inet_aton.c: Use #if 0, not #ifdef 0.
4159 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4161 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4162 to convert the returned value.
4163 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4164 the offset argument.
4166 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4168 Add new interface to catch/throw, usable from C as well as
4170 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4171 (scm_internal_catch): New function, replaces...
4172 (scm_catch_apply): Deleted.
4173 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4174 mechanism which is a bit more code, but can be used nicely from C
4175 and implement the Scheme semantics as well.
4176 (scm_internal_catch): This is the replacement; it's named after
4177 the analogous function in Emacs.
4178 (scm_catch): Reimplemented in terms of the above.
4179 (struct catch_body_data, catch_body, catch_handler): New
4180 functions, used by scm_catch.
4181 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4182 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4183 support for new cwdr.
4185 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4188 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4190 * acconfig.h: Added DYNAMIC_LINKING symbol.
4191 * configure.in: Add option and checks for dynamic linking.
4192 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4193 dynl.h: New files for dynamic linking support.
4194 * Makefile.am (libguile_a_SOURCES):
4196 (modinclude_HEADERS): Added "dynl.h".
4197 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4199 * init.c (scm_boot_guile_1): Call
4200 scm_init_dynamic_linking to initialize dynamic linking support.
4202 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4204 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4205 (as we Schemers say). It needs to be global, so that I can tweak
4206 it for the proper operation of unexec.
4207 (scm_boot_guile_1_live): New variable, see above.
4209 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4211 * guile-snarf.sh: Removed.
4212 * PLUGIN/guile.libs: Added dependency for -lm.
4213 * acinclude.m4: Renamed from aclocal.m4.
4214 * PLUGIN/greet: Removed.
4215 * Makefile.am, aclocal.m4: New files.
4216 * configure.in: Updated for Automake.
4218 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4220 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4221 and not top_level_lookup_thunk_var.
4223 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4225 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4227 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4229 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4230 Scheme function, instead of syntax. Single argument is now a
4233 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4235 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4236 scm_ra_divide): Properly terminate statements passed as arguments
4237 to IVDEP macros. (Thanks to Bernard Urban.)
4239 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4240 with non-constant sizes. (Thanks to Bernard Urban.)
4242 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4244 It's an "eval closure", not an "eval thunk." A thunk is a
4245 function of no arguments.
4246 * root.h (struct scm_root_state): Renamed
4247 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4248 (scm_top_level_lookup_closure_var): Renamed from
4249 scm_top_level_lookup_thunk_var.
4250 * root.c (mark_root): Uses changed.
4251 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4252 * init.c (scm_start_stack): Uses changed.
4253 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4254 Change scheme-visible name to *top-level-lookup-closure* from
4255 *top-level-lookup-thunk*.
4257 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4259 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4260 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4262 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4264 * gc.c (struct scm_heap_seg_data): Doc fixes.
4266 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4267 sweeping. Then, prepend each segment's free cells to its
4268 freelist, rather than wiping out the old value. (Thanks to Marius
4271 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4272 scm_check_freelist, scm_debug_newcell): New functions and
4273 variables, for debugging freelist problems.
4274 * pairs.h (SCM_NEWCELL): New debugging version added.
4275 * gc.h (scm_debug_newcell): Added extern declaration, used by
4276 debugging version of SCM_NEWCELL.
4278 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4280 On some systems <libc.h> conflicts with <unistd.h>, and should not
4281 be #included at all.
4282 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4283 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4284 * configure.in: Call it.
4285 * posix.c, filesys.c: Use its results to decide whether or not to
4287 * configure, scmconfig.h.in: Rebuilt with autoconf and
4290 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4292 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4293 pointer to the stdio stream before calling scm_setbuf0, so the
4294 latter will be able to retrieve it. I'm surprised this didn't
4295 segfault earlier. (Thanks to Christopher Lee.)
4297 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4299 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4302 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4304 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4305 number of stack narrowing specifier pairs. The first specifier in
4306 a pair controls inner border, the second the outer border. A
4307 number means cut that number of frames, a procedure object means
4308 cut until that object is found in operator position in a frame.
4310 * root.c (cwdr): Bugfix.
4312 * read.c: Recording of positions disabled by default.
4314 * procs.c (scm_closure_p): New function.
4316 * posix.c (scm_tmpnam): New function.
4318 * load.c: Added #include "throw.h".
4319 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4322 * load.c, load.h (scm_read_and_eval_x): New function.
4324 * eval.c: Renamed debug option "deval" to "debug".
4326 (scm_eval_x): `eval!' is no longer accessible from the scheme
4327 level. Motivation: We can't allow operations which introduce
4328 glocs into the scheme level. Guile's type system can't handle
4329 these as data. Use `eval' or `read-and-eval!' as replacement.
4331 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4332 SCM_CONSP since this is a macro!; Set vframe.prev to
4333 scm_last_debug_frame instead of 0. In this way we can look
4334 "above" the virtual start stack frame if we wish.
4335 (scm_debug_hang): New function: Useful for debugging Guile in
4336 certain tricky situations. Will probably be removed later...
4338 * debug.h: Changed semantics of debug option "backtrace". This
4339 option now only indicates whether we want automatic backtrace at
4342 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4344 * ports.c: #include "filesys.h"
4345 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4347 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4348 Motivation: This is system specific code which is related to file
4349 I/O. It also may use select. Added code by Gary Houston to
4350 detect presence of character in stdio buffers.
4352 * libguile.h: #include "libguile/libpath.h"
4354 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4355 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4356 SCM_SITE_DIR; Install libpath.h among the other include files.
4358 * load.c, load.h (scm_sys_package_data_dir): New function.
4360 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4362 * stacks.h: Bugfix: Don't use tail-array length field as stack
4363 length field! This screwed GC.
4365 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4367 * _scm.h: Added #ifndef around definition of macros min and max.
4369 * __scm.h: Added hooks for threads to plugin to in ints protection
4370 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4371 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4372 the main code in these macros duplicated and spread over multiple
4373 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4374 SCM_THREAD_SWITCHING_CODE.
4376 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4378 * snarf.h: New file.
4379 * guile-snarf.sh: New file.
4380 * Makefile.in (inner_h_files): Added snarf.h
4381 (ancillary, install, uninstall, distclean): Added actions for
4383 (.c.x): Use guile-snarf.
4384 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4385 (gen_c_files): Note that these depend on guile-snarf.
4386 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4387 now in "snarf.h". Added #include "snarf.h" to get them.
4388 * libguile.h: Added #include "snarf.h".
4389 (Patches applied and tweaked by Jim Blandy.)
4391 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4393 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4394 standards suggest against providing prototypes for system
4395 functions. Thanks to Greg Troxel.
4397 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4399 * strports.c (scm_eval_0str): New function.
4400 #include "read.h", to get prototype for scm_read.
4401 * Makefile.in (strports.o): Update dependencies.
4402 * strports.h: New prototype.
4404 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4405 scheme name from "int?" to "integer?". It seems to do the job.
4406 * numbers.h: Rename prototype too.
4407 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4410 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4411 scm_num_eq_p): Rename these according to R4RS conventions: call
4412 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4413 to making libguile R4RS compliant without ice-9...
4415 * load.c (scm_sys_search_load_path): Search for files under all
4416 extensions listed in the %load-extensions variable. If FILENAME
4417 is absolute, return it unchanged, without searching the load path.
4418 (scm_loc_load_extensions): New variable, pointing to
4419 %load-extensions' value cell.
4420 (scm_init_load): Initialize it, and the value it points to.
4421 (scm_primitive_load_path): Improve error reporting.
4423 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4424 of new Scheme variable %load-hook.
4425 (scm_primitive_load): Apply %load-hook to filename.
4427 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4429 * configure.in: add tests for figuring out whether buffered data
4430 is available in a FILE structure, which is needed by char-ready.
4432 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4435 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4436 exceptions using misc_error instead of syserror. It seems a bit
4437 odd to throw an exception if a string can't be found in the
4438 environment, but it's consistent with open-file, stat etc.
4439 (simpos.h): remove sys_ from getenv.
4441 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4442 occurs, throw an error instead of returning errno. Return value
4444 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4446 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4448 * filesys.c (scm_stat2scm): derive file type and permissions from
4449 the stat mode and append them to the returned vector.
4450 There isn't much overhead in doing this and it avoids the need to
4451 work with S_IRUSR et al. in Scheme.
4452 Define symbols scm_sym_regular etc.
4453 (scm_init_filesys): don't intern S_IRUSR etc.
4455 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4456 and s_primitive_load_path.
4458 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4460 * error.h: don't declare error symbols. prototype for scm_misc_error.
4462 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4465 * error.c: use SCM_SYMBOL to set up error keys.
4466 scm_misc_error: new procedure.
4468 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4470 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4471 between `#!' and `!#' is ignored.
4472 (skip_scsh_block_comment): New function.
4474 * feature.c (scm_set_program_arguments): New argument, FIRST.
4475 * feature.h: Update prototype.
4476 * init.c (scm_boot_guile_1): Pass new argument to
4477 scm_set_program_arguments.
4479 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4481 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4482 (scm_boot_guile): Call scm_set_program_arguments here, later than
4483 the old initialization.
4485 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4486 initialization procedure.
4487 - Delete in, out, err arguments; there are other perfectly good
4488 ways to override these when desired.
4489 - Delete result argument; this function shouldn't ever return.
4490 - Rename init_func argument to main_func, for less confusion.
4491 - Delete boot_cmd argument; main_func is more general.
4492 -Add 'closure' argument, to help people pass data to main_func
4493 without resorting to global variables.
4494 - Abort if reentered; don't bother returning an error code.
4495 - Call scm_init_standard_ports to set up the default/current
4496 standard ports; no need to pass them to scm_start_stack.
4497 - Remove code to evaluate the boot_cmd, and start the repl; let
4498 the user do something like that in main_func if they want.
4499 - Remove code to package up a return value; main_func can do any
4501 - Call exit (0), instead of returning.
4502 (scm_start_stack): Don't initialize the I/O ports here; that's
4503 weird. Delete in, out, err arguments. Move guts to
4504 scm_init_standard_ports, scm_stdio_to_port.
4505 (scm_init_standard_ports): New function, to set up current and
4506 default standard ports.
4507 (scm_start_stack, scm_restart_stack): Make these static.
4508 * init.h (scm_boot_guile): Adjust declaration.
4509 (scm_start_stack, scm_restart_stack): Remove externally
4510 visible declarations for these.
4511 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4513 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4514 written out several times in scm_start_stack.
4515 * fports.h: New declaration for the above.
4517 * feature.c (scm_set_program_arguments): New function.
4518 * feature.h: New declaration for the above.
4520 * ports.c: Formatting tweak.
4522 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4524 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4525 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4526 for obtaining the address of a car or cdr field. Motivation:
4527 &SCM_CXR make assumptions about the internal structure of the
4530 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4531 Motivation: see SCM_CXRLOC.
4533 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4534 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4535 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4536 Motivation: Safer use. Some other macros are defined in terms of
4537 these operations. If these are defined using the SCM_SETCXR
4538 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4539 to inefficiency and an <e1> with side-effects could potentially
4540 break. Also, these particular operations are heavily utilized in
4541 the garbage collector. In unoptimized code there will be a
4544 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4545 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4546 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4547 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4548 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4549 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4550 vports.c: Cleaned up use of pairs: Don't make any special
4551 assumptions about the internal structure of selectors and
4552 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4553 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4554 (Among other things, this change makes it easier to build Guile
4555 with certain compilers which have problems with casted lvalues.)
4557 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4559 * stacks.c: Improve selection of relevant stack frames when making
4560 a stack object. Introduce one level of indirection in the stack
4561 object to make it possible to "narrow" to a certain region of the
4562 stack. This facilitates making use of more clever algorithms (not
4563 implemented) for selecting relevant frames and gives a cleaner
4564 design since selection of frames can be done independently of
4565 extraction of frames from the real stack.
4566 (scm_stack_id): Also take #t as argument which means look at
4569 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4570 Turn n_tail into an integer directly representing current number
4571 of frames in stack. Add field tail.
4573 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4575 * debug.c (scm_make_memoized): Made it available at scheme level.
4576 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4577 SCM_NIMP before applying heavier predicates in argument checking.
4578 (scm_local_eval): Also take memoized object as argument.
4580 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4581 aren't created with zero length, but should such a strange
4582 creature suddenly turn up...
4584 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4586 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4587 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4589 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4591 * variable.c (scm_make_variable): Make the name hint optional, as
4593 (anonymous_variable_sym): Renamed from variable_sym. All uses
4596 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4597 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4598 of scm_primitive_load_path was also changed to
4599 "primitive-load-path", from "%try-load-path". Callers changed.
4600 We'd like to respect the convention that a function named
4601 "try-mumble" should behave just like the function called "mumble",
4602 but return #f instead of signalling some error.
4603 * load.h: Rename prototypes.
4605 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4607 * print.c (make_print_state, grow_print_state), print.h: Modified
4608 the print state representation: Don't use a tail array for
4609 recording of circular references. Resizing of the print state
4610 structure invalidates the print state pointer. To avoid passing
4611 around an indirect print state reference to all printing
4612 functions, we instead let the print state reference a resizable
4615 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4617 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4618 Don't crash when passed an improper list terminated by a
4619 non-immediate value.
4621 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4623 Allocate data for structures on an eight-byte boundary, as
4624 required by the tagging system.
4625 * struct.c (alloc_struct): New function.
4626 (scm_make_struct, scm_make_vtable_vtable): Call it.
4627 * struct.h (scm_struct_n_extra_words): Bump to 3.
4628 (scm_struct_i_ptr): New "field".
4629 * gc.c (scm_gc_sweep): When we need to free the data, use the
4630 information stored by alloc_struct to find the beginning of the
4631 block allocated to the structure, so we can free it.
4633 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4635 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4638 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4639 (scm_debug_info): New member: id.
4641 * stacks.c: Stacks are now represented as structs; Stacks have an
4642 id given to them by `start-stack'.
4643 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4645 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4646 Changed stack representation.
4648 * debug.c (scm_procedure_name): Try procedure property `name' for
4649 compiled closures aswell.
4651 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4653 * eval.c: scm_i_name moved to gsubr.c
4654 (scm_m_define): Record names of all kinds of procedure
4655 objects. (Earlier, only closures were recorded.)
4657 * procprop.h: Added declaration of scm_i_name.
4659 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4660 (scm_make_gsubr): Record names of compiled closures.
4662 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4664 * debug.c, debug.h: Removed obsolete code.
4666 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4667 stacks.c: Renamed regs --> scm_contregs.
4669 * print.c (scm_free_print_state): Cleanup print state before
4670 returning it to pool. It is better to do it here than in
4671 scm_prin1 since scm_prin1 is called often.
4673 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4674 s_set_source_property_x): Check that first argument is a pair or a
4677 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4678 scm_i_line, scm_i_column and scm_i_breakpoint global.
4680 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4681 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4684 * debug.h: Added debug object smob declaration and macro
4687 * configure.in: Build with backtrace.o and stacks.o if debug
4690 * Makefile.in: Added entries for new files: backtrace.c,
4691 backtrace.h, stacks.c and stacks.h.
4693 * symbols.c (scm_sym2ovcell): Fixed documentation.
4695 * _scm.h (min, max): Added.
4697 * async.c: Moved `min' macro to _scm.h.
4699 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4700 SCM_BACKTRACE_INDENT.
4702 * eval.c: Added new debug options `maxdepth' and `indent'.
4704 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4706 * print.h: Added selector SCM_PRINT_STATE.
4708 * print.c: New functions: scm_make_print_state,
4709 scm_free_print_state.
4711 * print.h: Added declarations for scm_make_print_state,
4712 scm_free_print_state.
4714 * debug.c (scm_m_start_stack): New acro.
4716 * debug.h: Small cleanup.
4718 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4721 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4743 declare functions with prototypes. (Patch thanks to Marius
4746 More prototype-related changes from Marius Vollmer:
4747 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4748 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4749 * ports.h (ptobfuns): Added prototypes. This means some casting in
4751 * fports.c: Added casts for initializations, since the functions
4752 are defined to take FILE * as their stream argument, not SCM.
4753 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4754 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4755 to `char *str_data' to conform to prototype.
4757 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4759 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4761 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4763 * stime.c, stime.h: use SCM_P method.
4765 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4767 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4768 be given at least two arguments. Insist that lst's last element
4769 be a list, but don't make any requirements of its predecessors.
4771 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4773 * eval.c (scm_nconc2last): Revert last change; there seems to be
4774 other stuff going on here.
4776 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4778 * eval.c (scm_nconc2last): Make sure that each element of lst
4779 (which is a list of argument lists, except for the tail) is a
4780 proper list, i.e., finite and terminated by '().
4782 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4784 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4787 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4788 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4791 * vectors.c (scm_make_vector): Fill vectors with the undefined
4792 value, to help make Guile Scheme code more portable to other
4795 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4796 * symbols.h, tags.h: Doc fixes.
4798 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4800 * async.c (scm_take_signal): Doc fixes.
4802 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4804 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4805 want to subtract it from the modulus; we just want to leave it
4808 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4810 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4813 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4815 * throw.c (scm_catch_apply): Finished implementation of
4818 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4820 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4822 (scm_init_filesys): set "i/o-extensions" feature.
4825 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4827 * Makefile.in (root.o): Correct dependencies.
4829 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4831 * Makefile.in: Added dependency entry for root.o.
4833 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4834 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4836 * init.c (scm_start_stack): Set initial root continuation number
4839 * procs.c: New function: scm_thunk_p.
4841 * procs.h: Added declarations of scm_thunk_p.
4843 * root.c: Renamed `call-with-new-root' -->
4844 `call-with-dynamic-root'.
4845 (cwdr): Removed allocation of new root state. This should be done
4846 separately by use of scm_make_root.
4847 (scm_apply_with_dynamic_root): New function: Does what it
4848 sounds like. Needed when spawning threads.
4850 * root.h: Added member last_debug_frame to root state.
4851 Added #include "libguile/debug.h"
4853 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4854 arguments. The motivation is that code in root.c needs catch
4855 functionality, and we want to avoid code duplication.
4856 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4857 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4858 handlers that run without popping the stack into the dynwind
4861 * throw.h: Added prototypes for scm_catch_apply and
4864 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4866 * root.h (scm_root, scm_set_root): Decouple thread support details
4867 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4868 SCM_SET_THREAD_LOCAL_DATA.
4870 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4871 and tortoise scanning loop.
4873 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4875 * Makefile.in: Rebuild dependencies.
4877 * libguile.h: #include "libguile/print.h" before "smob.h", since
4878 the latter uses the print_state structure.
4880 * throw.c (scm_ithrow): Use the correct variable when checking to
4881 see if a given element of scm_dynwinds is a valid catch.
4883 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4884 structure, abort; don't just silently ignore the garbage.
4886 * _scm.h: #include "print.h" here, since it seems to be used just
4888 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4889 strports.c, unif.h: Don't #include "print.h".
4891 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4893 * feature.h (scm_loc_features): Removed external declaration.
4894 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4896 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4898 * feature.c (scm_init_feature): Added threads feature (needs to be
4899 initialized here, since features doesn't exist when
4900 scm_init_threads is called).
4902 * libguile.h: Added #include "libguile/../threads/threads.h".
4903 (This is a kludge to get thread support working. This should be
4906 * configure.in, acconfig.h: Added flags for thread support.
4908 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4911 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4912 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4915 * _scm.h: Added conditional #include "threads.h"
4917 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4918 SCM_THREADS_SWITCHING_CODE.
4920 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4921 allocate the basic dynamic root object.
4922 (scm_boot_guile): Added call to scm_init_root.
4924 * root.c, root.h: Added root smob.
4925 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4926 functions: Implements dynamic roots mostly according to spec in
4927 SCM manual. Main difference is that the second argument is a
4928 throw handler rather than an error "thunk".
4930 * root.h: Added declaration of scm_init_root.
4932 * root.c: Added #include "genio.h", #include "smob.h", #include
4933 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4935 (scm_init_root): Added #include "root.x".
4937 * throw.c: Added #include "stackchk.h"
4938 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4939 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4940 can be used in scm_call_with_new_root; Added reenabling of stack
4941 checking when catching a throw.
4943 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4945 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4947 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4948 element is not found, as per R4RS.
4950 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4952 * list.c: Doc fixes throughout.
4954 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4956 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4957 declare the char * to be const. Avoids a warning in rgx.c.
4959 * ports.h: spelling fix.
4961 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4964 * load.c (scm_sys_try_load_path): throw an error if file not found
4965 (like it says it in NEWS).
4967 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4969 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4970 PROPS slot to '(), not #f; it's an empty alist.
4972 * throw.h, throw.c: Use SCM_P instead of #if hair.
4974 Remove special support for uncaught throws; see throw.c for
4976 * throw.c (uncaught_throw): New function.
4977 (scm_ithrow): Call uncaught_throw if we don't find a throw
4978 target; don't mess with scm_bad_throw_vcell.
4979 (scm_bad_throw_vcell): Variable deleted.
4980 (scm_init_throw): Don't initialize it.
4982 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4985 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4987 * numbers.c (scm_istr2int): If the number is short (as most
4988 numbers are), just call scm_small_istr2int to deal with it.
4989 (scm_small_istr2int): New function, created by un-#ifdefing the
4990 non-bignum version of scm_istr2int and renaming it.
4992 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4994 * load.c (scm_sys_try_load): don't check whether value returned
4995 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4996 Change the Scheme name from %try-load to primitive-load.
4998 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4999 Can avoid passing a message, allowing it to be derived in the
5000 error handler (e.g., if we want to throw to the key both from
5003 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
5005 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
5006 references now have a new appearance which is more compact and
5007 also gives a clue about what the target of the reference is.
5008 By setting parameters in the print state, more fancy printing can
5009 be achieved. This is used by the (not yet commited) backtrace
5012 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
5014 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
5017 * print.c: Added #include "struct.h". Removed function
5020 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
5021 scm_iprin1. Removed prototype for scm_prlist.
5023 * arbiters.c (prinarb),
5024 async.c (print_async),
5025 debug.c (prindebugobj, prinmemoized),
5026 eval.c (prinprom, prinmacro),
5027 filesys.c (scm_fd_print, scm_dir_print),
5029 mallocs.c (prinmalloc),
5030 numbers.c, numbers.h (scm_floprint, scm_bigprint),
5031 smob.h (scm_smobfuns),
5032 srcprop.c (prinsrcprops),
5034 unif.c, unif.h (scm_raprin1, rapr1),
5035 variable.c (prin_var): Changed argument `int writing' to
5036 `scm_print_state *pstate'.
5038 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
5039 that it will be called before scm_init_print.
5041 * print.c (scm_prin1): Print states are now allocated when calling
5042 scm_prin1 and then passed around to all printing functions as an
5043 argument. A cache `print_state_pool' enables reuse of print
5045 (scm_make_print_state): New function.
5046 (scm_iprin1): Adaption to print states.
5047 (scm_iprlist): An initial "hare and tortoise" scan brings down
5048 time complexity to O (depth * N). (Better time complexity will be
5049 achieved when the printing code is completely rewritten.)
5051 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5053 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
5054 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
5055 it gets done whether or not the cache variable has a value.
5057 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5059 Distinguish #f and ().
5060 * __scm.h: #undef SICP.
5061 * pairs.h (SCM_EOL): Delete this definition, equating it with
5063 * tags.h (SCM_EOL): Give it a new definition here; I think I found
5064 the value it used to have. Doc fixes, too.
5066 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
5068 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
5069 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
5070 Lord's implementation of structs, allowing for tail arrays as
5071 described in the manual. Also fixed some bugs. (Both the interface
5072 and the implementation should be improved.)
5074 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
5076 * print.c, print.h: Closures now print like #<procedure foo (x)>.
5077 People who whish to see the source can do `(print-enable 'source)'.
5078 Removed #ifdef DEBUG_EXTENSIONS.
5080 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5082 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
5083 integer (assuming for now accepting an integer is a good thing).
5085 * error.c, fports.c: replace use of %S in lgh_error args with %s.
5086 %S will be used instead for write'ing arguments.
5088 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
5089 asserts. fix a few other asserts.
5090 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5091 scm_uniform_vector_ref, scm_array_set_x,
5092 scm_dimensions_to_unform_array): change args in
5093 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5094 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5095 scm_substring_fill_x): likewise.
5096 gsubr.c (scm_gsubr_apply): likewise.
5097 eval.c (SCM_APPLY): likewise.
5099 * eval.c (4 places): replace scm_everr with lgh_error or
5102 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5103 scm_memory_error): new procedures.
5104 scm_everr: deleted. can use scm_wta, dropping first two args.
5105 scm_error: convert NULL subr to SCM_BOOL_F.
5107 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5110 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5113 * error.c, error.h: new error keys: scm_arg_type_key,
5114 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5116 scm_wta: reimplement using lgh_error instead of scm_everr.
5118 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5120 * gdbint.c: scm_lread now has one more argument.
5122 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5123 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5124 loading source from non-file ports, which, e. g., happens when
5125 using the Emacs interface).
5127 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5130 * read.c: Added code for recording of positions of source code
5131 expressions; New functions: recsexpr, scm_lreadrecparen;
5132 _scm_make_srcprops --> scm_make_srcprops
5133 (scm_flush_ws): Removed updating of positions counters. This work
5134 is already done by scm_gen_getc
5136 * read.h: Added prototype for scm_lreadrecparen
5138 * print.c: Added #include "alist.h"
5140 * eval.c: Added #include "hash.h"
5142 * eq.c: Added #include "ramap.h"
5144 * options.c: Documentation fixes.
5146 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5147 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5148 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5149 --> scm_make_srcprops
5151 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5152 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5153 function calls in the definition of the whash access macros.
5155 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5157 * init.c (scm_boot_guile): Add level of indirection to
5158 scm_boot_guile_1() to ensure that stack base pointer is properly
5159 initialized. There was no guarantee that variable i was the
5160 highest/lowest variable on stack (i.e. the call frame of
5161 scm_boot_guile was not completely protected from gc).
5163 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5165 * ports.h (scm_port_table): put back file_name, it will be used to
5166 support debugging. Undo related changes in fports.c, ioext.c,
5169 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5171 * ports.h (scm_port_table): remove file_name member for now, it seems
5173 * fports.c (scm_open_file): don't set file_name in PTAB.
5174 (prinfport): don't use file_name in PTAB.
5175 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5176 * ports.c (scm_add_to_port_table): don't intialize file_name.
5177 (scm_port_file_name): remove for now.
5178 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5180 * fports.h (scm_mkfile): prototype deleted.
5181 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5183 * debug.c, unif.c: use scm_out_of_range instead of
5184 wta for range errors (ASSERT still needs work).
5186 * error.c, error.h (scm_out_of_range): new procedure.
5188 * error.c, error.h (scm_out_of_range_key): new key.
5190 * posix.c (scm_sync): #else was missing.
5192 * error.c, error.h: append _key to names scm_num_overflow and
5195 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5196 of consing an empty list.
5197 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5198 of macros, saves code and string space.
5199 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5200 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5201 lower case. Rename scm_syserror_m to scm_syserror_msg.
5202 error.h: prototypes for new procedures.
5204 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5206 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5208 * error.c, error.h: setup scm_num_overflow key.
5210 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5211 Remove definition of SCM_OVSCM_FLOW.
5213 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5215 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5216 explicit message and args.
5218 * error.c, error.h, __scm.h: change system_error_sym to
5221 * error.c (system_error_sym): remove leading %% from the Scheme name
5224 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5226 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5228 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5229 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5230 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5231 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5232 renamed. (These were introduced by unsupervised name
5235 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5237 * print.c: Added code for detection of circular references during
5238 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5239 a hook for printing of closures (accessible via print options).
5240 This leads to a split of calls to scm_iprin1 into two classes:
5241 elementary print operations (e. g. the code which prints a smob)
5242 still use scm_iprin1 while top level calls (like scm_display) use
5243 scm_prin1. scm_prin1 begins by clearing the data structure used
5244 to record reference information.
5246 * print.h: Added declarations of scm_prin1 and scm_prlist.
5248 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5250 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5252 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5254 * error.c (err_head): scm_iprin1 --> scm_prin1
5256 * debug.c: Adjusted header comment.
5260 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5262 * strerror.c: Doc fix.
5264 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5266 * gdbint.c (gdb_read): Now possible to run during GC.
5267 (unmark_port, remark_port): New functions.
5269 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5271 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5272 of allocating a new string object. Also, increase size by
5273 the factor 2 instead of 1.5.
5275 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5277 * __scm.h (SCM_P): Corrected to run under traditional C.
5279 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5282 * async.c: Calls to scm_sysintern corrected.
5284 * async.h (scm_async_clock): Redundant declaration removed.
5286 * continuations.c (scm_dynthrow): Redundant declaration removed.
5288 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5289 Definition typos corrected.
5291 * debug.h: Missing declarations of functions in debug.c added
5294 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5295 Missing declarations to functions in eval.c added.
5297 * filesys.c: Possibly uninitialized variable rv.
5299 * gc.h (scm_object_addr, scm_unhash_name): Missing
5300 declarations of functions defined in gc.c added.
5302 * genio.c: Possible typos str_data -> wstr_data. ???
5304 * genio.c: Possibly unintended shadowing of local variable
5305 `int c' (gotos out of scope of inner `c'). ???
5307 * init.c: Uninitialized `SCM last' may be used.
5309 * ioext.h: (scm_sys_isatty_p): Typo.
5311 * list.h (scm_list_head): Missing prototype for function in
5314 * numbers.c (scm_two_doubles): Changed from extern to static
5315 (is used only within numbers.c).
5317 * numbers.h: Repeated declarations removed.
5319 * ports.h (scm_close_all_ports_except): Declaration for the
5320 function defined in ports.c added.
5322 * posix.h: Missing declarations added.
5324 * procs.h (scm_make_subr_opt): Missing declaration added.
5326 * socket.h (scm_sys_gethost): Missing declaration added.
5328 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5330 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5331 Missing declarations added.
5333 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5335 * struct.c: Uninitialized variable `SCM answer' may be used.
5337 * unif.c (l2ra): Declaration prototype.
5339 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5340 defined in ramap.c).
5342 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5343 Redundant declarations removed (they are in ramap.h).
5345 * variable.h (scm_make_udvariable,
5346 scm_make_undefined_variable): Declaration corrected to
5347 correspond variable.c.
5349 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5350 Missing declarations added.
5352 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5354 * Makefile.in (distclean): Don't forget to delete fd.h.
5356 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5358 * fd.h.in, tags.h: Trivial cleanups.
5360 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5361 marksweep.h just declared functions from gc.c.
5362 * gc.h, libguile.h: Don't #include "marksweep.h".
5363 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5364 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5365 dependencies updated.
5367 * libguile.h: Don't #include "files.h"; it's been deleted.
5369 * files.c (scm_sys_delete_file): Moved to filesys.c.
5370 File is now empty; deleted.
5372 * filesys.c: scm_sys_delete_file is now here. Remove
5373 #if's; they seem to rely on remnants of an old portability
5374 regimen. If the problems come up again, solve them properly,
5375 using autoconf. Specifically: Don't test M_SYSV, and #define
5376 remove to be unlink if it's #defined; don't use remove just
5377 because HAVE_STDC_HEADERS is #defined.
5378 * filesys.h: Add declarations for scm_sys_delete_file.
5379 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5380 files.o, files.h, files.c, and files.x.
5381 * init.c: Don't #include "files.h", and don't call scm_init_files.
5383 Use SCM_P instead of PROTO; the latter intrudes on the user's
5385 * params.h: Deleted; definition of SCM_P moved to...
5386 * __scm.h: ... here, where it replaces PROTO macro.
5387 * libguile.h, smob.h: Don't #include "params.h".
5388 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5389 smob.h: Fix prototypes accordingly.
5390 * Makefile.in: Update dependencies.
5391 (inner_h_files): Remove params.h.
5393 * gc.c: #include "gc.h"; every module should include its header,
5394 to let the compiler cross-check the declarations against the
5397 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5398 simpos.h: #include "libguile/__scm.h".
5400 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5402 * init.c: Don't forget to #include smob.h and init.h.
5403 * Makefile.in: Dependencies updated.
5405 * smob.h: Use PROTO instead of #if __STDC__.
5407 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5409 * __scm.h: Doc fixes.
5411 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5412 <angles>; this allows `make depends' to work properly.
5414 * libguile.h: #include smob.h and pairs.h before the others; they
5415 define typedefs used by other headers.
5417 C files should #include only the header files they need, not
5418 libguile.h (which #includes all the header files); the pointless
5419 recompilation was wasting my time.
5420 * Makefile.in (all .o dependency lists): Regenerated.
5421 * libguile.h: Don't try to get a definition for size_t here...
5422 * __scm.h: Do it here.
5423 * _scm.h: Since this is the internal libguile header, put things
5424 here that all (or a majority) of the libguile files will want.
5425 Don't #include <libguile.h> here; that generates dependencies on
5426 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5427 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5428 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5464 "unif.h", "throw.h", "tag.h", "symbols.h", "struct.h",

5519 * unif.c: Get "unif.h", "feature.h", "strop.h", "sequences.h",

5524 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
5525 * weaks.c: Get "weaks.h".
5527 * stackchk.h: #include "libguile/debug.h",
5529 * print.h, read.h: #include "options.h", since everyone who uses
5530 either of these files will need that.
5532 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5533 anyone who uses this file will need them to define the smob
5534 printing functions. Also, get markers.h, since people will need
5535 to #define the mark functions.
5537 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5538 * ports.h: ... to here.
5540 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5541 don't rely on archaic C default type rules.
5543 * fports.h: #include "libguile/ports.h", since you need that in
5544 order to parse this.
5546 * genio.h: #include "libguile/print.h", because you need that to
5547 parse this; don't bother #including "ports.h", since print.h gets
5550 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5552 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5553 this; it's now a reference to an element of *scm_root.
5555 * debug.h: Don't #include "options.h"; the compiler won't be able
5556 to find that once the headers are installed; instead, #include
5557 "libguile/options.h".
5558 * gc.h: Same, with marksweep.h.
5559 * mbstrings.h: Same, with symbols.h.
5560 * scmhob.h: Same, with _scm.h.
5561 * smob.h: Same, with params.h.
5563 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5564 C files; there's no need for this, and it forces recompilations
5567 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5569 * error.c (scm_error): declare scm_error_callback.
5571 * error.h: prototype for scm_error_callback.
5573 * __scm.h: define lgh_error.
5574 (SCM_SYSERROR): redefine using lgh_error.
5576 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5578 * error.c (scm_error): new procedure.
5580 * error.h: prototype for scm_error.
5582 * Makefile.in (install): install scmconfig.h from the current
5583 directory, not $(srcdir).
5585 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5587 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5588 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5589 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5590 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
5591 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
5592 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5593 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5594 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5595 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5596 vports.h, weaks.h: #include "libguile/__scm.h", not
5597 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5598 dependencies are within libguile properly.
5600 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5602 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5603 when scmconfig.h doesn't exist.
5605 * load.c (scm_sys_try_load): Correct spelling.
5607 * feature.c (scm_loc_features): Make this static.
5609 * Makefile.in (libpath.h): Omit trailing slash from path. We
5610 shouldn't require it of users, so why put it here?
5612 Move code to initialize and search %load-path from ice-9 to C
5613 code, so we can use the load-path to find the ice-9 boot code;
5614 this makes it easier to run Guile without installing it. See
5615 corresponding changes in guile/Makefile.in.
5616 * feature.c: Move stuff concerned with the load path to load.c.
5617 (scm_compiled_library_path): Deleted.
5618 Don't #include libpath.h here.
5619 * feature.h: Don't mention scm_compiled_library_path.
5620 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5621 <sys/stat.h>, and <unistd.h> (if present).
5622 (R_OK): #define if the system hasn't deigned to.
5623 (scm_loc_load_path): New variable.
5624 (scm_init_load_path, scm_sys_search_load_path,
5625 scm_sys_try_load_path): New functions.
5626 (scm_init_load): Initialize scm_loc_load_path to point to the
5627 value cell of the Scheme %load-path variable.
5628 * load.h: Add declarations for scm_sys_search_load_path,
5629 scm_sys_try_load_path.
5630 * init.c: Call scm_init_load_path.
5631 * Makefile.in (feature.o, load.o): Dependencies updated.
5633 * load.c, load.h: Rewrite using PROTO macro.
5635 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5637 * gc.c (scm_cellp): New function: C predicate to determine if an
5638 SCM value can be regarded as a pointer to a cell on the heap.
5640 * gc.h: Added declaration of scm_cellp.
5642 * gdb_interface.h: New file: The GDB interface header from the GDB
5645 * gdbint.c: New file: GDB interface.
5647 * gdbint.h: New file: GDB interface.
5649 * libguile.h: Added #include <libguile/gdbint.h>.
5651 * init.c (scm_boot_guile): Added scm_init_gdbint.
5653 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5654 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5655 found if object files and source are kept separate).
5657 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5659 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5661 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5663 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5664 TK_SRC_DIR; they're not relevant any more.
5666 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5667 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5669 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5671 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5672 search path, so we can find the <libguile/MUMBLE.h> headers.
5674 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5676 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5677 implicit in the .c.o rule.
5678 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5681 Put the library path in a header file, instead of passing it on
5682 the command line in every compilation.
5683 * Makefile.in (libpath.h): New target.
5684 (feature.o): Depend on libpath.h.
5685 (clean): Delete libpath.h.
5686 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5687 * feature.c: ... #include "libpath.h" here.
5688 * .cvsignore: Ignore libpath.h.
5690 Don't install the unwashed masses of Guile header files in the
5691 main #include path; put most of them in a subdirectory called
5692 'libguile'. This avoids naming conflicts between Guile header
5693 files and system header files (of which there were a few).
5694 * Makefile.in (pkgincludedir): Deleted.
5695 (innerincludedir): New variable; this and $(includedir) are enough.
5696 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5697 (installed_h_files): Divide this up. Now this variable lists
5698 those header files which should go into $(includedir) (i.e. appear
5699 directly in the #include path), and ...
5700 (inner_h_files): ... this new variable says which files appear in
5701 a subdirectory, and are referred to as <libguile/mumble.h>.
5702 (h_files): List them both.
5703 (install): Create innerincludedir, not pkgincludedir. Put
5704 the installed_h_files and inner_h_files in their proper places.
5705 (uninstall): Corresponding changes.
5706 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5707 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5708 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5709 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5710 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5711 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5712 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5713 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5714 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5715 vports.h, weaks.h: Find __scm.h in its new location.
5716 * __scm.h: Find scmconfig.h and tags.h in their new locations
5717 (they're both "inner" files).
5719 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5721 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5723 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5725 * posix.c: Doc fixes.
5727 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5729 * socket.c: Don't include a prototype for inet_aton; just use a
5730 K&R style declaration, to avoid warnings but minimize the chance
5731 of conflicts with the system.
5733 On NextStep, <utime.h> doesn't define struct utime, unless we
5734 #define _POSIX_SOURCE before #including it.
5735 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5736 * acconfig.h: New comment text for above CPP symbol.
5737 * configure.in: Call it.
5738 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5740 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5742 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5743 testing for __EMX__.
5745 * posix.c: #include <libc.h>, if it exists.
5747 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5748 don't even know if the latter exists.
5750 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5751 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5752 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5754 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5756 (scm_init_posix): Use them when initializing the Scheme constants
5759 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5761 * Makefile.in (libdir, includedir, bindir): Use the
5762 autoconf-supplied values, instead of deriving them ourselves.
5763 (pkgincludedir, datadir, pkgdatadir): New variables.
5764 (install, uninstall): Put the header files in a special
5765 subdirectory, not in the main search path.
5767 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5768 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5770 * Makefile.in (IMPLPATH): Deleted; never used.
5772 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5773 on the Tcl/Tk source any more.
5774 (INCLUDE_CFLAGS): Remove references to the above.
5776 * Makefile.in (version.o): Corrected dependencies.
5778 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5780 * libguile.h: #include "version.h"
5782 * init.c (scm_boot_guile): Call scm_init_version.
5783 * gscm.c (gscm_run_scm): Call scm_init_version.
5785 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5786 GUILE_VERSION): AC_DEFINE these.
5787 (acconfig.h): #undef the above symbols.
5789 * Makefile.in (libobjs): Add version.o.
5790 (installed_h_files): Add version.h.
5791 (c_files): Add version.c.
5792 (gen_c_files): Add version.x.
5793 (version.o): New rule.
5794 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5795 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5796 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5797 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5798 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5799 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5800 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5801 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5802 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5803 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5804 weaks.o): Add version.h to dependency lists.
5805 (markers.o): Remove duplicate rule.
5807 * version.h: New file.
5809 * version.c: New file.
5811 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5813 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5814 array; use it appropriately. Since GCC is quite happy to
5815 subscript functions, it never warned us about this; we should use
5816 -Wpointer-arith in the future. I guess we never tested
5819 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5821 * socket.c: Doc and copyright fixes.
5823 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5825 * debug.c: Fixed and improved gdb support.
5827 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5829 * socket.c: Added declaration of inet_aton to avoid compiler
5830 warning. (Hope this solution is correct.)
5832 * stime.c: Added declaration of ftime. (This is missing in
5835 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5837 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5839 * Makefile.in (c_files): add strerror.c.
5841 * strerror.c: new file from Emacs' sysdep.c.
5842 maybe configure should also check for sys_errlist.
5844 * configure.in (AC_REPLACE_FUNCS): add strerror.
5846 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5848 * debug.c (scm_init_debug): Added initialization for
5849 scm_evaluator_traps.
5851 * debug.h, debug.c: Various name changes.
5852 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5853 "debug-options-interface". See commentary in options.c.
5855 * options.h, options.c: Options now have documentation strings.
5856 Also added a long explanatory commentary.
5858 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5861 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5862 last_debug_info_frame is now updated in all cases.
5864 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5867 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5869 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5870 Added option STACK_CHECKING.
5872 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5874 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5876 * __scm.h: Removed symbols for debugging support.
5878 * acconfig.h: Added symbols for debugging support.
5880 * configure.in: Added user option for debugging support.
5881 --enable-debug will include the debugging code into libguile.a.
5883 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5884 scm_relocate_chunk_to_heap.
5886 * debug.c: New file: low-level debugging support. It also
5887 includes support for debugging with gdb. (The extensions to gdb
5888 are written by Per Bothner at Cygnus.)
5890 * debug.h: New file: low-level debugging support.
5892 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5893 argument pairs. Extensive modifications to the debugging
5894 evaluator. Added "SECTION:" commentaries to clarify what happens
5895 when, during double compilation. Renamed EVALIMP --> EVALIM.
5896 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5897 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5898 the beginning of the file. New procedure: scm_unmemocopy.
5899 Added some global state variables needed by the debugging
5900 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5901 check_entry, check_apply, check_exit, debug_options and
5902 evaluator_traps. New acro: undefine.
5904 * eval.h: Renamed EVAL --> XEVAL.
5906 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5907 --> scm_make_weak_key_hash_table.
5909 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5910 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5912 * libguile.h: Conditionally include debug.h
5914 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5915 scm_object_properties shouldn't return handle. `handle' now gets
5916 initialized in scm_set_object_properties_x. scm_object_properties
5917 doesn't any longer create an entry in scm_object_whash.
5919 * options.c: New file: handling of run time options.
5921 * options.h: New file: handling of run time options.
5923 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5925 * print.c: New procedure: scm_print_options
5927 * print.h: Defines for print options.
5929 * read.c: New procedure: scm_read_options
5931 * read.h: Defines for reader options.
5933 * root.h: Added scm_source_whash among scm_sys_protects.
5935 * srcprop.c: New file: source properties.
5937 * srcprop.h: New file: source properties.
5939 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5940 (Bug found by A. Green.)
5942 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5944 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5946 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5948 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5950 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5951 and should be called by the final client.
5953 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5955 * gc.h: Use the PROTO macro when declaring functions.
5956 * gc.c: Use the PROTO macro when declaring static functions.
5957 Remove the CPP hair around function definitions.
5959 * gc.c (scm_init_storage): Initialize scm_asyncs.
5961 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5962 preprocessor symbol; "__scm.h" is where it might get #defined.
5963 * __scm.h: Similar: #include <scmconfig.h> before testing
5966 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5968 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5970 * init.c (scm_boot_guile): Add init_func argument; call
5971 (*init_func) instead of calling scm_appinit; it's ucky to
5972 hard-code names for the user's procedures.
5973 * init.h (scm_boot_guile): Adjust declaration.
5975 * __scm.h (PROTO): New macro, for declaring functions with
5978 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5979 eliminate all the __STDC__ conditionals.
5980 (scm_boot_guile): Add declaration.
5981 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5982 Remove __STDC__ conditionals around function definitions; the
5983 declarations in init.h will provide the same information, more
5986 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5987 complain about it in the error message; the error message is
5988 adequate without that note, and there's nothing the user can do
5991 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5993 * Makefile.in (ancillary): Drop def.sed.
5995 * posix.c (scm_init_posix): Use numeric values, rather than
5996 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5997 F_OK. The symbols aren't available on some systems, and I'm
5998 pretty sure their values are fixed by common widespread practice.
5999 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
6001 More functions unavailable on some systems.
6002 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
6003 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
6005 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6006 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
6007 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
6008 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
6009 stub that signals an error as the #else.
6011 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
6013 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
6015 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
6017 * unif.c: include ramap.h.
6019 * read.c (endif): case_insensative_p renamed case_insensitive_p.
6021 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
6023 * ports.c: include sys/ioctl.h.
6025 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
6027 * configure.in: check for sys/ioctl.h.
6029 * ports.c: include <malloc.h> not "malloc.h".
6031 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6033 * fports.c: remove ttyname and tmpnam declarations.
6035 * posix.c: fewer ttyname declarations.
6037 * fports.c: include <string.h> not "string.h".
6039 * init.c, ioext.c: include string.h and unistd.h.
6041 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6043 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
6044 genio.c, simpos.c, vports.c: include string.h.
6046 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
6048 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
6050 (scm_addr_buffer_size): change type from scm_sizet to int.
6051 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
6052 from scm_sizet to int.
6054 * error.c: include unistd.h.
6056 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
6059 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
6061 * __scm.hd, def.sed: deleted.
6063 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
6065 Changes for NeXT, suggested by Robert Brown.
6066 * configure.in: Call AC_TYPE_MODE_T.
6067 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
6068 NeXT. Put header file list in alphabetical order.
6069 * configure, scmconfig.h.in: Regenerated.
6070 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
6072 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
6075 * acconfig.h: New file, providing documentation for the CPP
6076 symbols defined in configure.in
6077 * acconfig-1.5.h: Removed; superceded by the above.
6079 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
6081 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
6083 * fports.c (scm_open_file): don't return #f, throw error.
6085 * ioext.c (fileno): renamed from %fileno.
6086 (soft-fileno): deleted.
6088 * ports.c (scm_port_revealed): don't need to check for -1 from
6090 (scm_set_port_revealed_x): return unspecified, not #f.
6092 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
6094 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
6096 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
6098 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
6100 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6102 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
6103 This is necessary on Ultrix, and doesn't hurt portability.
6105 * Makefile.in (dist-dir): New target, implementing a new dist system.
6106 (installed_h_files): Put in alphabetical order.
6107 Remove duplicate entries for markers.h and unif.h.
6108 (c_files): Remove duplicate entries for markers.c.
6109 (ancillary): Renamed from anillery; all uses changed. Remove
6110 PLUGIN; it's a directory, and needs special treatment in dist-dir.
6111 Remove all the ../doc/* files; doc/Makefile.in handles that.
6113 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6115 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6116 every if must have an else, or else the whole command has a
6117 non-zero exit code whenever the if's condition is false.
6119 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
6121 * posix.c: include string.h.
6123 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6125 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
6128 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
6129 Remove leading % from scheme names.
6130 Do not return error values, call SCM_SYSERROR or similar.
6132 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
6134 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
6136 * struct.c (scm_init_struct): new file.
6138 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
6140 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
6141 (scm_list_head): added list-head for rapidly chopping argument
6142 lists off of longer lists (and similar).
6144 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
6146 * objprop.c (scm_object_property): assq the cdr of the whash
6147 handle for obj, not the handle itself.
6149 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
6151 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
6152 weak hash tables last of all marking to avoid an obscure gc bug.
6153 WARNING: circular lists stored in a weak hash table will hose us.
6155 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
6157 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
6158 new functions similar to scm_substring_move_left_x and
6159 scm_substring_move_right_x.
6161 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
6163 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
6166 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
6168 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
6170 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
6172 * strports.c (scm_strprint_obj): convenience function. C for
6173 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
6175 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
6176 removed to a separate library
6178 * init.c (scm_boot_guile): copied from guile-tcl.c.
6179 Initialization specific to tcl interpreters removed.
6181 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
6183 * ports.c (scm_ports_prehistory): size malloced here doesn't
6184 matter so long as it is non-0 (got rid of "* 4").
6186 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
6188 * gscm.h: gscm_mkarray eliminated (presumably was not being used
6189 since its definition was bogus).
6191 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
6193 * mallocs.[ch]: back again (for rx at least).
6195 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
6197 * ports.c: removed functions relating to the mapping between ports
6198 and descriptors. (That stuff is unix-specific and should be collected
6199 in a separate library).
6201 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
6202 (Tom Mckay@avanticorp.com)
6204 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
6206 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6207 handled correctly (SCM_FREEP was applied to them) -- test for
6208 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
6209 being overwritten with #f. (brown@grettir.bibliotech.com)
6211 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
6213 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
6214 for a specific symbol or for all symbols.
6216 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
6218 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
6219 keys and weak values confused).
6221 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
6223 * list.c (scm_last_pair): map '()=>'()
6225 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
6227 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
6228 Generalized assoc and hash-table functions.
6229 Factored pairs.c into multiple files.
6231 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
6233 * gscm.c (gscm_run_scm): got rid of objprop.
6235 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
6237 * genio.c (scm_getc):
6238 NOTE: fgetc may not be interruptable.
6240 * procprop.c (scm_stand_in_scm_proc):
6241 NOTE: don't use a alist here.
6242 (scm_set_procedure_properties_x): fix type checking throughout this file.
6244 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
6246 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
6247 after freeing part of the port table.
6249 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
6251 * strports.c (scm_mkstrport):
6252 * vports.c (scm_make_soft_port): allocate a port table entry
6253 (possibly triggering gc) before setting the tag of the corresponding
6256 * pairs.c (scm_delq_x): never throw an error.
6258 * vectors.c (scm_make_vector): made the default vector fill argument
